I have him as my #1 QB on one of my teams with Flacco as the backup.
Now that hes out for 2-3 months or more do you think its a good idea to drop him and pick up another QB now instead of hoping to find a decent QB to pick up later?

Right now I see these QBs available:
Matt Cassel
Donovan McNabb
Ryan Fitzpatrick
Matt Hasselbeck
Kerry Collins
Colt McCoy
Alex Smith
Cam Newton
Andy Dalton
