I agree that once Vick is healthy, get him out there. It gets him more experience in playing time which could be valuable down the road...
Regardless though as I have said all along and got criticized for earlier in the season, unless Vick plays Defense also, the Falcons still won't win consistantly enough to turn this season around. Vick can be the difference in some close ones, but not the past two weeks where teams can pass and run all over this horrible defense.
