I think whats more disturbing is that players have to hide the fact that they have concussions. Something should be done about that. Nobody should have to hide an injury. The article citing Colt McCoy, he should have never gone back into the game anyway. Thats whoever is in charges fault and James Harrison who applied the hit. They are adding doctors on the sideline which is needed. 28 out of 44 NFL players said that its safer than it was in 2009.
How about stricter penalites on helmet to helmet hits? Better equimpment like what was mentioned above. How about maybe a weight restriction so a 300 lb guy doesnt sack a 150 lb guy? That might cause a concussion or two.
Only issue I would have would be the incidental H2H hits ...
The officials should look at that in the first place, stop the play and look at it to see if it was indeed intentional or incidental, there are also incidental H2H hits that are being called, while others not.
