Why Don’t NFL Teams Pay NBA Players to Block Kicks?

Recently I listened to an episode of Freakonomics Radio where they talked about specialization in the NFL. Specifically, they were talking about how the long snapper position has become something that NFL teams specifically draft for and pay upwards of $1 million a year to have on their 53-man roster. This got me wondering: what other positions are ripe for specialization in the NFL?

This train of thought brought me to the field-goal unit. Not the kicker, holder, or snapper, but the defense. What if teams hired the tallest guy money could buy to do one thing: block kicks? It’s so obvious that I assumed there must be a reason teams aren’t doing it, or at least trying it. This sent me down a rabbit-hole of heights and wingspans, standing reaches, verticals, salary caps, and something I’m not very good at: geometry.

So why don’t NFL teams pay a really tall guy to block field goals for them?

Is Blocking A Kick Just By Being Tall Even Possible?

My assumption for hiring a tall guy to block kicks is that he wouldn’t need to work hard to do it. In my experiment, he doesn’t even cross the line of scrimmage. He just stands there, arms raised, and jumps to try to swat the ball down. So is this even a feasible strategy? How high does the ball travel over the line of scrimmage? Obviously kicks get blocked, but usually the defender has some penetration. What if he was at the line of scrimmage?

Thankfully I didn’t have to break out the geometry textbooks to figure this one out. I used this nifty website to calculate exactly how high the ball would be above the line of scrimmage at different kick angles. The assumption here is that the ball is on a straight upward trajectory as it crosses the line of scrimmage, and that the kick is taken from 7 yards out. Here are some heights at various kick angles.

Angle (Degrees)Height at Line of Scrimmage (Feet)

According to one study, the optimal launch angle for a kick is between 38 and 45 degrees, as this will maximize distance. Thus, we can assume that kickers are going to be aiming for that angle. Of course, human error and misjudgment will mean that some kicks go below or above that ideal range.

Graph from the University of Nebraska study which found that even at different kick speeds, 45 degrees was still the optimal angle.

So according to our geometry and assumptions about the ideal angle, most balls will be flying over the line of scrimmage 21 feet in the air, far out of the reach of even the tallest NBA players. But, at launch angles of 35 degrees or lower, we have a glimmer of hope, maybe.

Let’s take a famous big guy in the NBA: Boban Marjanovic. The 7’4″ center has a 7’10” wing span, and a 10’2.5″ standing reach. He’s one of the few NBA players able to dunk the ball without even jumping. He has just a 23″ vertical leap, putting his overall potential range at 12’1.5″. A truly enormous human being. It’s hard to comprehend. However, he’s barely tall enough to block a 30° kick, and that’s with a perfectly-timed jump.

With that being said, it’s highly probable that Marjanovic gets his hand on at least one kick during the season, and if he can make it even half a yard toward the kicker, he takes the vertical height down a cool foot, making it that much easier.

There were just 14 field-goals blocked in 2021, out of 1066 field-goal attempts, meaning just 1.3% of all field goal attempts at any distance were blocked. Honestly, that’s higher than I was expecting. I think it’s reasonable to assume that our tall guy could attain at least that and maybe a half-point to a point higher over the course of a season.

There would also likely be psychological effects on the kicker of having such a large human towering over the line of scrimmage, and the kicker may subconsciously put unnecessary height on the ball, decreasing its horizontal travel. This would especially be apparent early on, when it’s a new phenomenon for the kicker and they have not seen this type of player in front of them before.

One other logistical challenge in blocking a kick is that it’s not a given, even if the ball is low enough, that your center gets a hand on the ball. What kind of reaction time would be necessary to accurately block a kick from the line of scrimmage?

According to a highly cited paper, a field goal travels around 19-22 m/s, or 21-24 yards/s. Meaning the ball will reach the line of scrimmage in approximately .33 seconds. That’s about 80ms longer than the average human reaction time, meaning our NBA center could reasonably have some reaction to the ball in that time. How much is another story, but with good positioning I don’t hate our chances.

So all-in-all, I think we can safely say it’d be difficult, but not impossible for a big guy to block kicks from the line of scrimmage, and that over the course of the season, he’d probably block one or two and influence many more.

The Existing Arguments Against Having A Designated Tall Guy

I did a quick Google search and didn’t see any in-depth statistical analysis or mathematical justifications on the subject. The most common argument I found on some reddit threads against the idea was “roster spots are limited” and “roster spots are valuable and blocked kicks are not”. However, we already know that teams are willing to dedicate a whole roster spot to a guy who snaps the ball 8-12 times a game. And he’s not even scoring… they pay him to prevent a slip-up that costs them points; my guy would be paid to actively prevent the other team from scoring.

My own kin, Drew, offered another argument:

"I also wonder if having someone like that would cause more fakes because it kind of takes him out of play as a defender since those guys usually can't run"

Aside from some hurtful accusations he’s making about the speed and agility of big guys, he makes a point. This could be an unintended side-effect of implementing this kind of player. We see this with all elements of the game: someone innovates, and then a few years later the league adapts and the competitive advantage largely disappears. But for the sake of my argument, I’m going to assume that teams wouldn’t immediately be able to exploit this tactic just because there’s one tall guy on the field.

So that left a few questions: how valuable is a blocked kick, and how much should teams be willing to pay for one?

How Valuable Is A Blocked Kick?

In 2021, NFL teams had an average total cap of around $187 million, and scored 391 points on average. So they paid about $478,000 per point last season. This is one way to value blocked kicks. By blocking a kick, you’re preventing 3 points (maybe 2.61 points if you consider that the median FG% in 2021 was 87%. However, you could also argue that a blocked kick sets the offense up with a better chance to score, and that change in expected points should be attributed to the blocker, but let’s keep this simple for now.) So each blocked kick could be valued at approximately $1.434 million (3 points * $478k per point). I’m assuming that the going rate for a point prevented is the same as the rate for a point scored (which you could argue isn’t the case since defensive players aren’t paid the same as offensive players).

Another way to look at it is by cost per win. The median cap spend per win in 2021 was $21 million. The median points required to win a game was 29. So that gives you a cost of $724k per point, if we’re after wins (which most teams are). This would give even greater value to a blocked kick ($2.2 million)!

What NBA Players Could NFL Teams Afford?

Much to my satisfaction, we could actually afford our Serbian center Boban at his modest $3.5 million per year. Using our second valuation, he would only have to block two kicks all year to be worth the investment. If we use our points-based valuation, it would be 3 kicks blocked over the course of a season.

A younger, more athletic Mo Bamba would cost NFL teams a premium at $7.5 million per year, so he’d need a higher output to justify the cost. At that rate, we may even ask him to rush the kicker a bit or maybe even get in for some corner fade routes in the red zone.

At 7’1″ and only $2.1 million a year, Bol Bol may be a great investment for some NFL team looking to make a splash on special teams. But wait, could these guys actually block that many field goals in a season?

There are usually several field goal attempts per game (the top 32 kickers averaged 1.93 field-goal attempts per game). The average team made 32.1 field goal attempts in 2021. Using that 1.3% block rate, we would expect the average team (not individual) to block .42 field goals per year. If you’re paying $724k per point, that means you’d only want to pay a designated kick-blocker $304k per year since that’s likely to be his output. Given the NFL salary cap minimum for 2022 is $705k, that’s not feasible.

Let’s assume our tall guy makes your team twice as good at blocking kicks, from a 1.3% to 2.6% block rate. Now, he’s still blocking under 1 kick per season at .83. Maybe you can afford the league minimum at this point, but that’s it.

At this point, I’m feeling a little deflated. I think there’s a reason nobody is trying this. Blocked kicks are rare, and kickers kick the ball high above the line of scrimmage most of the time. So unless you can find a 7-footer that’s also fast and can rush the kicker a bit, and doesn’t cost a fortune, it’s probably not worth it over your two-way guys that can contribute in multiple ways for the team. However, if you find a 7-footer that can also stand in the endzone and cherry pick some passes, then this argument changes a lot.

  1. What about a player like Kevin Durant coming off of the edge to block kicks. Still have the benefit of the wing span plus they cover a lot of ground with the stride. Always seems like the block from the edges is just a second away from being successful


    1. I think he would be great with his height plus athleticism, but he’d be way too expensive for any NFL team unless he’s willing to block kicks as a hobby!


  2. 2 things.
    1) I think someone that we don’t know would be the ideal person for NFL teams. Someone who played in college and is athletic as Vince Carter but can’t shoot or defend. He probably plays in the G-League because his athleticism puts butts in the seats but he’d rather be the guy jumping over the center during a field goal, he just doesn’t realize it.
    2) Why did ya’ll stop the ELO posts? I followed them almost religiously last season and then didn’t really do any betting this year. Stopped by to see if you had one for the bowl games and I saw you didn’t post any this season.


    1. Hey Mitchell, thanks for your support and for your comments. I agree with you on 1)… you could definitely get an athletic and tall person that isn’t cut out for the NBA but could easily block kicks for a reasonable price.

      As for our ELO posts, 2022 was a hectic time for us. We posted on Twitter at the beginning of the season that we wouldn’t be doing much but should have updated the site as well. Sorry about that. We’re hoping to be more active for the 2023 season but I can’t promise that we’ll bring back Elo-related content. Elo is now easily accessible from CollegeFootballData.com (https://collegefootballdata.com/exporter/ratings/elo?year=2022) so we don’t feel it’s adding much value, plus it’s such a simplistic model that we can do much better by adding more data where available.

      I doubt we’ll be doing the every-week rankings, bets, etc. that we used to do, but will hopefully do more in-depth stuff that’s more unique and less rinse-repeat.

      Thanks again for reading!
