players are just too damn big
There was a discussion in another thread (click here) about Roger Goodell and the potential for kickoff elimination as a way to curb concussions.
My thought* (which I shared in that thread) was simple: if the powers that be really care about concussions, there is probably one real way to address them: by imposing a maximum weight for playing football. The thinking is this: players are simply just too big and fast these days.
Of course, there are a lot of possible nuances to such a scheme, including different limits per position, and what the actual limits should be. Your idea goes here!
My feelings on Goodell's positioning is that it all relates to potential lawsuit deflection, i.e., concrete small actions he can point to saying "look, we have been trying to make it better!" The real problem lies in something more fundamental: huge, fast men bashing heads over and over. Unless that changes, concussions, for better or worse, are likely here to stay.
That, or some kind of awesome weird big football helmets.
* - actually my wife suggested this. She is pretty smart though.
