Tim Tebow (Florida)
There have been many great college football players in recent years, but perhaps none of them have been as famous — for many reasons — as Tim Tebow. The three-time All-American, two-time SEC Player of the Year and two-time BCS national champion won the Heisman Trophy in 2007. However, many NFL scouts believed he would be a very poor fit at quarterback at the professional level, and that Tebow would have to change positions to enjoy a long pro career.
Spurning that idea, Tebow tried his hand at quarterback in the NFL, with very limited success. While he did lead the Denver Broncos to a playoff win in his second season (2011), by 2012, he was out of the league. There was a brief moment where he was signed by the Philadelphia Eagles in 2015 in training camp, but he never made the team’s final roster. He saw limited action with the New York Jets, but that didn’t materialize either.
