Fitz is a guy who has always been a starter. but he doesn't perform, with any qb, be it Skelton or Kolb. He gets double teamed when he shouldn't, and his targets are minimal. the cardinals have an anemic offense.
Right now it's about points. Denarius Moore had a touchdown last week, and very reasonably could get another one. Fitzgerald, for as talented as he is, is a major gamble.
Last question I'll ask, and I'm going with Vick, i think, but:
Vick against the Falcons
Cam Newton against the Bears or
Alex Smith against the Cardinals
and don't ask me how I have 3 qb's.
