Tim Tebow
Not all of the career revivals on this list lasted long. Tebow was one of the NFL’s most polarizing quarterbacks during his time with the Broncos. In the end, he crashed out of the football world and joined the New York Mets. That was the last we expected to see of him.

But Urban Meyer had other ideas and lured him back to practice camp in 2021. He offered his former Florida star the chance to compete for a tight end position. Meyer received criticism for turning the camp into a circus. Finally, the Jaguars cut Tebow (via Bleacher Report).
