Why not? It's 41-7. This is probably the last chance he'll have to get live snaps.
Because he's not the second team QB, and the guy that IS the second team guy, got two passes and a few handoffs. For the season, he has less than 5 passes.
That's just stupid.
Tennessee is one play away from Crompton being in there, and they are letting someone that doesn't even need to be on the field, in the game.
