Think Kyler Murray is too damn short to be a successful QB in the NFL?
YOU'RE WRONG ... so says fellow short guy Doug Flutie, who's telling TMZ Sports he's living proof that the vertically challenged can THRIVE in the pros!
Flutie is 5'10" -- which is a good height among normies but short by NFL quarterback standards.
Murray is also 5'10" -- and the knock on the Heisman Trophy winner is that he just doesn't have the height to make the tough throws over those gigantic NFL linemen.
