When it comes to individual performances in the NFL Ed Oliver Jersey , people only seem to talk about quarterbacks when it comes to championships that define their careers. but running backs have not gotten the same treatment over the years.Running back is still a glamorous position, with a lot of media attention going toward the position, but yet rings don’t get discussed as much. There have been some great running backs that haven’t won the Super Bowl, with much of the all-time leading rushers missing out on that elusive ring. The media and fans don't tend to place as much blame on a running back's shoulders for a team's failure to win a Super Bowl. This is due to quarterbacks having the ball in their hands the most, hence the outcome of the game weighs on them more than others. Another reason is that the roles of running backs today are not what they once were. We're seeing more and more teams operating with "running backs by committee" or teams simply simply throwing the ball more and more. Even when they're on the one-yard line with less than a minute left and the most bruising running back in football just needing that one yard to win his team a Super Bowl. But at least Marshawn Lynch does indeed have a Super Bowl.Which ones were the best to ever play without a championship? Here are the 15 best without a Super Bowl championship, and most of them have never made an appearance in the big game. We’re only looking at running backs that played their entire careers in the Super Bowl era Cody Ford Jersey , so Jim Brown doesn’t make this list, because he never had a chance. He did help Cleveland win their last NFL Championship, in 1964. Every year there are some NFL players that analysts, coaches and fellow competitors alike, expect great things from, who simply don't get the job done. More often than not, successful players last a few years and slowly lose their effectiveness and retire in their early to mid thirties. Quarterbacks may last a bit longer Devin Singletary Jersey , but many still leave the league early. JaMarcus Russell, one of the most notorious draft busts of all time was, in essence, an NFL non-contender after just a couple of years in Oakland.Russell is just one example, and unfortunately, for every long NFL career, there are many short ones. In many cases Dawson Knox Jersey , a player may have a decent year, be signed to a new contract and then, for whatever reason, stop performing. In other cases, these players may be signed as backups to different teams, but in essence, their career as an impact player in the NFL is over. If they are not signed Brian Burns Jersey , they may enter the ocean of free agency. So while we don't predict each of these young players being cut next season, we do predict that many of them will not see time as consistent starters again in the NFL, that 2014 is a negative turning point in their careers, and very possibly the start of the end of their professional careers.This list contains ten young players that may not have a significant future in the NFL after the 2014 season. This does not mean that they will remain unsigned and float off into obscurity, but this list will be for those 2014 players who have earned a good chance of either unemployment or a permanent backup job. The reasons for these changes of duty may be chronic injury, poor play, penalties and suspensions Greg Little Jersey , or some painful combination of the three. "Young" is somewhat of a subjective term but given that the average age of NFL retirees is 28 or 29 (depending on your source), we've focused on players 27 years old and under.This list is very subjective and will likely offend some of you, so I send over some death threats and fury in the comments section. If not, a reasoned, well thought out counter-argument works too.
