Tim Tebow
Speaking of Tebow, the former Florida Gators quarterback was another one-season wonder himself. Skeptics questioned whether Tebow’s unorthodox throwing mechanics and play style in college would translate to the NFL, but Broncos head coach Josh McDaniels took a chance, drafting him in the first round in 2010. He got his opportunity to start in 2011, and for a short time he silenced his haters by taking Denver from a 1-4 start to an 8-8 finish and a Wild Card Playoff berth, where he orchestrated a blockbuster win against the Steelers. Peyton Manning arrived in 2012, though, and Tebow couldn’t make it work in stints with the Jets, Patriots, and Eagles.
