Stevan Ridley
Over the last decade, Bill Belichick has become infamous for (among other things) his unpredictable use of running backs, and Stevan Ridley is one of the prime examples. The second-year running back was the Patriots’ leading rusher in 2012 with over 1,200 yards and 12 touchdowns, but the following year was a totally different story. Several early-season fumbles put Ridley in Belichick’s doghouse, costing him significant playing time, and 2014 added injury to insult when Ridley tore his ACL. He’s now out of the NFL after a few years of sparing use as a backup.
