Absolutely not. Back when I played there wasn't emphasis on concussions. If a player comes to me concussed that's it for him. That being said, if I am a player in the NFL who wants to stay in the league, sometimes you have to play through things and keep your mouth shut. Players have been using that tactic for years. Its a brutal contact sport my friend and Kolb just doesn't have the toughness like others. 5 bucks says Kelly played through them and the list most likely goes on and on. When you feel the need to personally attack someone for no reason, I most certainly let you know the person typing at the other end suffers from a myriad of disabilities. It really isn't relevant to the discussion, just your personal attack. Enjoy your day man. I am off to golf its too nice out.
