Over the past two seasons, he has gained 844 yards on 148 carries (5.7 YPC) and found the end zone 12 times (11 rush, 1 rec). In fact, among running backs with at least eight rush attempts inside the opponent's 5-yard line over the past two seasons, Gillislee is tied with LeVeon Bell for the highest touchdown conversion rate (70.0%) in the league. Gillislee's arrival takes a lot of the wind out of Rex Burkhead's sails. Burkhead was probably going to see most of the goal line work, but given Gillislee's talents in that are, he'll probably handle those duties. Double digit touchdowns are possible if Gillislee holds down that role for the entire year. It's going to be tough to predict the Patriots' backfield on a weekly basis. In Buffalo, this cements LeSean McCoy's status as a top 5 fantasy back since he's now likely to see an increase in goal line attempts. Jonathan Williams likely serves as his primary back up, though the Bills may address the position in the draft.
