8. Jerry Rice (2000)
One of the greatest wideouts in NFL history, Rice was phenomenal for the Niners. However, they released him because he was old and they paid him a lot of money. San Francisco wanted to restructure their roster and it made sense to get Rice off their books. Then, he walked away as a free agent and joined the Oakland Raiders. It looked like it was the end.

Rice’s move to the Raiders was a success because he helped them return to the playoffs. The wideout’s influence on the franchise was profound. They got to the Super Bowl but lost out against Tampa Bay. Meanwhile, Rice made the Pro Bowl too. The craziest thing was that he was 40 at the time. The Raiders even listed the veteran on their all-time roster despite his short tenure.
