Pointless; you're improving from a level that is unimaginably terrible to a level that is also unimaginably terrible. The difference in effects downstream of the incident being counted ("can the player remember where he lives?") is likely to be much smaller than the difference in incidents, because for most purposes there is no difference between the pre- and post-treatment results.
I see that in 2011 there were 32 NFL teams and a team can field no more than 11 players at a time. If I assume an average of 352 concussions a year, one per year per "stylized active player" - and I would bet the number is higher - a reduction of 25 per year is basically meaningless. That would correspond to a reduction in concussions per player-year from 1 to about 0.93, or if the rate of concussions was three times as high as I assumed above, from 3 to 2.9.
As far as the preschool studies go, people like to use them to argue that the same intervention should have some kind of beneficial effect when applied to normal students whose average lifetime incarcerations are zero. There is no justification for this.

Really, I'd say those 25 people are very happy to not have concussions. You're begin extremely crass just dismissing the health of 25 people.
Which I guess can happen if you look at things strictly through a stats lens and not a personal impact one

Sometimes it's more important to recognize whether anything meaningful has been accomplished than whether people have their hearts in the right place.
If you'll notice, I did explicitly treat player health, as opposed to concussion count:
