I agree with you about the IR, he should be able to play sooner then the IR designation would have allowed. But thoughts of Sam's future as a player in the NFL has had to have crossed the Packers organizations minds. If it hasn't, then they are wearing some really big blinders and Green and Gold tinted glasses. Both Sam and the Packers may be viewing this optimistically and willing to roll the dice that he won't concuss again, but I bet there are some doctors out there holding their collective breaths.
I know after AR had his concussion there was a lot said about his new helmet and how it would help prevent another one, I assume they have Sam wearing the most protective head gear known to man, anyone else read anything about that? If there is such a helmet, why isn't every player wearing one?
