No. 10 Doug Flutie
Bears, Patriots, Bills, Chargers
Flutie hasn't had the kind of career the other QBs on this list have, but when he has seen action, he's been the ultimate scrambler. At 5-10, Flutie is hard for pass-rushers to pin down and most of his best throws have come on the run. His elusiveness has kept him working in the NFL into his 40s. Flutie is expected to back up Tom Brady in New England this season.
