I was making a general comment about concussions for college football players. If medical doctors clear Sam to play in this instance, I have no problem with him playing.
In general though, if concussion protocol changes so that there is a mandatory amount of time that must pass after a player is diagnosed with a concussion, I'd be in favor of erring on side of caution for players that are this young, for injuries that could affect them the rest of their lives.
I think championship college football teams need to be 2 deep at EVERY position.
As for Ash, I'm no doctor but could the migraines be a result of so many concussions? Do we even know at this point?
