Top 20 NFL Players Whose Careers Seem Doomed

National Football League careers end each and every year. Many players find that they ride off into the sunset without much fanfare, in part because they did not make significant impacts on the field during meaningful games. Practice squad players who are unable to earn spots on depth charts ahead of more talented athletes are eventually forced to face the reality that their dreams of being NFL superstars who one day help a franchise win a Super Bowl are sadly never going to be realized. Some of those individuals attempt to salvage their careers via the Canadian Football League, while others simply move on to other endeavors away from the sports world.

Age is, of course, the great equalizer in the sports world, a foe that is undefeated and untied. That enemy of great athletes everywhere will, sooner than later, catch up with the man who is arguably the greatest regular season quarterback in the history of the NFL. There has been plenty of speculation leading up to Super Bowl 50 regarding the future of that QB who has not, as of the posting of this piece, announced his attentions past the final football game of the 2015-16 season. It seems, at this stage, that it would be best for everybody if he respectfully ended his playing career during the current winter.

So many others in history have squandered opportunities to play in the NFL and chances at stardom. This includes a pair of wide receivers who, for whatever reasons, have struggled to understand what the NFL allows players to do away from the field. One of those two men still has a chance to save his career and prove his doubters wrong, but only if he is able to stay away from trouble. Last but certainly not least is a young quarterback who was once hoped to be a savior of a franchise. Instead, he may never again take the field if certain rumors about his personal demons are accurate.

At least one journalist, Marla Ridenour of, believes that the problems affecting Cleveland Browns quarterback Johnny Manziel are far more serious than immaturity and a love of partying when he is not on the football field. Manziel has never been punished by the NFL, but his being linked with a second domestic incident in under four months seems to have been the breaking point for the Browns. Manziel was one of the most fun quarterbacks in all of college football during his days at Texas A&M, but the Browns cutting him in March could be the beginning of the end of his NFL career.
