I may be totally wrong about this, but it seems to me that if Vick was that great still, he would've been starting already. The people who see him in practice all day everyday for weeks and months at a time thought Kevin Kolb was a better starting quarterback. This will be his first start in four years. And let's not forget that Vick isn't 24 any more. Like I said, I could be wrong, but I'd prefer to stick with the more known quantity, take my 280 yards, one or TDs and the INT you'll get from Romo.
I got to say, though, if you have to have a problem, yours is a nice one to have.
