Quinn has missed the last two games with a concussion and he’ll have to wait before he can take the field in the post-Jeff Fisher era. After missing time with other injuries this year, Quinn’s 2016 season ends with an efficient four sacks in just nine games. After missing half of the 2015 season, Quinn hopes to come back strong and healthy in the New Year. When he’s on the field and playing at 100%, Quinn is one of the most intimidating young edge defenders in the league.
Quinn showed his true potential in 2013 when he earned First-Team All-Pro and Pro Bowl honors as he tallied 19 sacks. He also received a tremendous 98.8 overall grade from Pro Football Focus. He came back down to earth a bit in 2014, but he still racked up 10.5 sacks on his way to yet another Pro Bowl selection.
Without Cunningham, the Rams are left with three running backs on the roster: Todd Gurley, Malcolm Brown, and Chase Reynolds.
