Jonas Gray
Calling Jonas Gray a “one-year wonder” would be an extremely generous statement, because, in reality, Gray was nothing more than a “one-game wonder.” Little more than an afterthought in the MASH unit that was the running back group for the New England Patriots during the 2014 season, Gray led the team in rushing with a paltry 412 yards. To make matters worse, he accumulated almost half of those yards (201) in one Sunday night game against the Indianapolis Colts.
From that game on, Gray had a total of just 260 rushing yards — including the postseason — for the remainder of his NFL career. New England thought so little of Gray that they let him go after the 2014 season, and after brief stints with the Miami Dolphins and Jacksonville Jaguars, Gray was out of football by the end of 2015.
