re: FYI: There were more injuries among the top 20 "slow-paced" teams last season...

I think one way to test the hypothesis that defensive players are more likely to be injured when facing no huddle offenses is to look at how many injuries occur during long, sustained drives (in terms of number of plays) against no huddle offenses, and see how many of those injuries occur to players who have not been substituted. If they can show that players are more likely to be injured toward the end of those drives, then the hypothesis sticks, maybe.

But here's the thing: if a player hasn't substituted, then he has had more plays than someone who has substituted. You would need to try to correct for the difference in number of plays, and you'd have to prove that it's the lack of substitution and the fatigue associated with playing down after down without a break. It could just be that players who can't substitute are in the game for more players, and are therefore more likely to get injured during a game.

It's very complicated and it's not easy to pin down. Maybe they have sufficient data for this, but without that data, none of us on the SEC Rant can really say for sure what's right.

If you just compare teams and not individuals then you cannot really get an accurate picture of what's going on. You need to know, for a fact, that injuries are occurring to due fatigue, and not just from the number of plays in which an individual participates.
