as was seen with Derek Anderson and Matt Barkley, you can get just about anybody off the street in a pinch to come lose a game (or win if you play the jets). If your goal isn't winning games, it's a viable option.
It's no less dire than the giants, who have eli's corpse (strangely reanimated last night... someone get him tested), Alex Tanney (who went to Monmouth of Illinois, a known football powerhouse), and something called a Kyle Lauletta - a 4th round fetus from the university of richmond who is in the dog house after getting arrested over a traffic violation (and "other" offenses). Most qb depth charts are kind of terrifying if you pick up the rock they're hiding under.
