I've largely avoided commenting on this issue, but there a few things I thought worth pointing out:
1) I was very impressed with how Braxton Miller handled it. I hate Ohio with the heat of 1000 Suns, but I tip my cap to him there. Very mature and responsible to lay as still as possible until the situation was under control -- as opposed to Gholston's own teammate who crawled out of there.
2) We have had similar situations in the past at Michigan where a player was <stunned>, but in those instances we took the player out of the game. I don't know if this was a medical team call or a coaches call, but I remember RichRod of all people doing this at least two times -- once with Tate and once with Denard. I was shocked that MSU allowed Gholston back in the game at the time and remain so now. The potential for long-term damage just isn't worth putting him back in the rest of the game.
