Jerome Harrison
Running back Jerome Harrison had a slow start to his career in Cleveland, but he turned it on in the last three games of the 2009 season filling in for injured starter Jamal Lewis. During this span he amassed an incredible 561 rushing yards and 5 touchdowns, including a 286-yard, 3-touchdown game that saw him break a Cleveland record previously held by the legendary Jim Brown. Unfortunately, we never got to see what Harrison could do over a full season, as complications from a brain tumor forced him to retire early in 2011.
