Holy Crap! I have never been so worried about a rookie getting injured in the pre-season as today!
But yes, quite the conundrum, how long does he play, and if very little or none and they go with a guy that's been here 2 days, does that make it pretty much a wasted game? How can they use this to evaluate anyone, you know the guy can't have much more than 4 or 5 plays to run, can he?
Then what if he gets hurt? Do we even have anyone who could run a wildcat type offense to get through the game, at least?
