Tim Tebow
Admittedly, it’s weird to think about Tebow as a one-season wonder because he’s an unforgettable part of football history. But in terms of his NFL career, that’s exactly what he was. The only time he shined was during that magical stretch during the 2011 season when he somehow willed the Broncos to six straight wins, which turned out to be just enough to get them to the playoffs. He capped it all off with that memorable 80-yard touchdown pass to Demaryius Thomas on the first play of overtime to beat the Steelers.
But that was the end of the line for Tebow in the NFL. The Broncos traded him the following off-season when they landed Peyton Manning. Tebow never did much with the Jets and eventually left football altogether in order to chase a baseball career. He spent four years playing in the minor leagues before becoming a sports commentator and working on his charity initiatives.
