Mark Ingram
Here is another good NFL player who failed to live up to all the hype. Mark Ingram was in the NFL for nearly a whole decade. This hard runner only went past 1,000 yards in a season three times. It is even worse to hear that he only played a full 16 game schedule thrice. In 2019, the Ravens took him in. His workload was more limited than it already was, but he did exceed 1,000 rushing yards for the third time.
Desmond Howard
In college, Desmond Howard played for Michigan. He was a junior when he bagged the Heisman Trophy in 1991. While he was a talented guy, this did not save him from having among the most disappointing careers on the list. He had been with the Washington Redskins when he had his best playing year in 1994. That was when he caught 40 balls for 727 yards and made five touchdowns. To be fair, this is a decent record. However, we expected more from him since he was a Heisman Trophy winner.
