4. DeMarco Murray (2014)
The Dallas Cowboys shocked their fanbase when they released their star running back. This came after the most productive season of his career. However, Murray priced himself out of a contract renewal. Jerry Jones had a choice between keeping Dez Bryant or Murray and went for the former. Murray’s father Kevin signaled his surprise that the Cowboys allowed his son to leave (via Dallas Morning News).

In the end, Murray was delighted to depart because he made his fortune. The Philadelphia Eagles offered him a five-year contract worth $42 million. Murray thought that this would suit him perfectly and duly signed up. But he had the least effective year of his career and they traded him to the Titans at the end of the season.
