That's not a very good way to judge special teams. For instance, just looking at the box score shows Marshall's punt unit as averaging 43.8 yards per punt, which is solid from the outside view. However, the box score also makes an error by showing no touchbacks. In reality, there was a touchback- a big one which resulted in only a 19 yard net (punted from the FAU 39, after touchback, FAU got the ball at the 20).
Averages aren't nearly as good as other stats. Unfortunately, those other, far more important stats only exist to a select few. This may bore many of you, but it is some good stuff that I may have touched on earlier on this board:
Example 1:
For instance, if that punt from FAU's 39 yard line had been downed at the 1 yard line, it would have been only a 38 yard punt. From the outside, that is not a good punt. In reality, downing a ball at the 1 yard line would be gaining 100% of the available distance you could have. So even though the punt unit would have been perfect in terms of what it could do, the 38 yard punt would negatively impact their average.
A far better statistic to look at it how much the punt unit netted based on the percentage of available yards that they could have gained on a punt.
Example 2:
Another instance of bad special teams stats: kick coverage coverage. There are two measures of this, one of which is really bad and one of which is slightly less bad.
Assume Team A kicks off from the 35 yard line. The ball lands at Team B's 20 yard line (a sky kick). The return is for only 8 yards. Based on one common statistic used for kick return coverage, that means the kick coverage team would have only allowed an 8 yard return. At that rate, they'd lead the country. However, in reality, they are allowing the opposing offense to start at the 28 yard line, which would put them near the bottom of kick coverage units.
Now, assume another team (Team C) kicks the ball from their 35. It lands at team D's goal line. Team D returns the ball to their 20 yard line. Based on a common statistic to measure kick return coverage, Team C just allowed a 20 yard return. However, the opposing team starts the ball at their 20 instead of the previous example at the 28 yard line.
Which kick coverage team was better? Clearly, it's better to keep your opponent at the 20 yard line than it is the 28 yard line, but a common measure of ranking kick coverage units would show Team A as doing a better job than Team C.
Example 3:
Last year, Marshall's kick coverage unit ranked #13 according to the NCAA stats. According to the NCAA stats, they were 3rd in C-USA behind UTEP and FAU. According to the NCAA, UTEP had the top ranked kick coverage unit in the conference:

However, if you go to the C-USA website, you will see that UTEP had the worst (#14) ranked kick coverage unit in the conference:
http://conferenceusa.com/stats.aspx?path=football&year=2017
How can one team be ranked as top in the conference according to one reputable source by ranked last in the conference in the same thing according to another reputable source? It's because there are too many morons in this world. And unfortunately, there are just as many morons who are coaches who don't understand this, look at the stats that are illogical, and think their schemes/systems are right because of it.
In the above example, the NCAA stats are ranking a kick coverage team based on how many yards they allow on the return. The C-USA website ranks the same statistic based on the net yardage (how many yards the ball was kicked and how many yards the ball was returned deducted from it).
The C-USA way is far better and more logical but still misses a big hole . . . and this is where the really good shit comes in. The important measure is where the opposition starts their drive. That's the only thing that matters. However, how important is starting from the 15 yard line compared to say, the 19 yard line? We will get to that.
Pretend Team E allows their opponent to start at the 12 yard line after every kickoff. That would be phenomenal, and the defensive coordinator would be cool with giving half of his salary to the kick coverage coach. Now, pretend that Team F allows their opponent to start at the 13 yard line after every kickoff. Again, that would be amazing coverage. Which team would do a better job? The obvious answer, by a yard, is Team E, right? Well, statistics are still missing a huge part of the story.
Pretend that Team E didn't cause a single turnover in kick coverage all year. On the other hand, Team F caused 2-4 turnovers on kick coverage throughout the year. Is getting 2-4 turnovers, especially that close to your opponent's end zone, better than giving up one more yard per kick return on average? I would think so. But you can't simply "think." You have to know. Just how valuable is it to give your offense the ball on your opponent's 10 yard line, 14 yard line, or 20 yard line? I'd think that is pretty damn important. But again, thinking isn't good enough. Show me proof.
I have it.
For every single game between two FBS teams over the last ten years, I have the starting location and results of each drive. Garbage drives (those at the end of a half or game when a team isn't trying to score) are excluded from it. I have the percentages of what happens for every drive that started from your own 1 yard line to your opponent's 1 yard line in terms of any type of score, a field goal, a TD, a punt, etc.
The fact that Marshall's kick coverage unit caused 2-4 turnovers last season resulted in almost automatic points based on where they gave their offense the ball. That pushes their unit over another unit that may have allowed a one yard lower average on opponent's starting field position.
When you take all of the important factors into consideration and take the time to detail all of these drives, Marshall had the best kick coverage unit in the country last year.
In other words, I know that based on tens of thousands of drives, there is very minimal difference in allowing a team to start on their own 28 yard line instead of their own 25 yard line. What does that mean? It means that moronic head coaches who are content kicking a ball deep and allowing the return team to get it at the 25 are doing a disservice to their team. They could sky kick it to a defensive end in the second line, still give up a 13 yard return, and really lose nothing from it in terms of giving the opponent a higher chance of scoring. On the other hand, they could gain a ton by forcing a non-skill player to try to catch a ball, put the ball in the hands of a guy who isn't used to carrying it, and even possibly getting the ball to land on the ground since a defensive end isn't going to have much experience knowing when to catch the ball or let the real returner go after it.
