18. Steve Smith
After 13 seasons with the Carolina Panthers, most people assumed he would spend his entire career there. However, Carolina released him at the end of the 2013 season despite the fact that he was still an important part of their offense. The Panthers wanted to adjust their wage cap structure and made the decision to sacrifice Smith. But Smith was furious because he found out on the radio (via Business Insider).

2005 was the best year of his career. Smith led the league in both receptions and receiving yards. He also won the Comeback Player of the Year award. But he wasn’t finished. The wideout continued to give his all for the Baltimore Ravens for three seasons. This shows that no football player can take their future for granted because things can change overnight.
