Jonas Gray
Another crazy New England running back story, Jonas Gray is really more of a one-game wonder than a one-season wonder. On November 16, 2014, only Gray’s fourth game on the Patriots’ active roster, he filled in for LeGarrette Blount and ran all over the Colts for 201 yards and four touchdowns. He had a whopping 37 carries in the game, a feat since surpassed only once by Le’Veon Bell. Despite his performance, Belichick gave Gray just 20 carries throughout the rest of the season and released him at the start of 2015. Gray was never able to find a long-term fit with another team.
