11. Blaine Gabbert
The draft is always a gamble. For every Peyton Manning, there’s a Ryan Leaf. Meanwhile, some of the league’s greatest talents only emerge in the ensuing years. Tom Brady is a shining example. But Gabbert stung the Jaguars for a couple of reasons. The quarterback was a No. 10 pick in 2011. They drafted him after he starred for the University of Missouri (via Slate).

Jacksonville traded up six places to land the signal-caller. This proved to be a massive mistake because he was trash. He maintained a shoddy 53.3 passing percentage rate. Furthermore, he threw 24 interceptions with just 22 touchdowns. The team won just five of his 27 games as a starter. Meanwhile, the Houston Texans drafted future Hall of Famer J.J. Watt with the next pick.
