I think if you're going with the run and gun QB model, I'd take Vick over Tebow. Big question is what kind of $$$ Vick will be looking for. I could see Tebow as a backup, and use him as a Wildcat option. I don't know if these guys could help KC win any more games, but maybe next year they can get a franchise QB. Thye could also see who is around in the 2nd and 3rd rounds, maybe get lucky with a late pick QB. Let Vick or whoever start, ease the new QB in.
Whatever happens, they have to get a plan in place to get a franchise type QB, you have to have that QB in today's NFL.
I'd look at Matt Flynn also, currently on Seattle's bench behind Wilson.
