Andrew Luck
During his brief career, Luck was a Pro Cowl candidate for three straight seasons, and he led the NFL in passing touchdowns with a record-best 40 touchdown passes. All he was missing was a Super Bowl ring, and in 2015, fans figured it would finally be his year. Unfortunately, four weeks into the season, Luck proved to be rather un-Lucky when he suffered a shoulder injury and had to drop out of an NFL game for the first time as a result. He briefly returned for three subsequent games, but he suffered yet another injury, which was pretty much the nail in the coffin for Luck’s once-promising career.
