Nick Chubb rushed 15 times inside the 5-yard line for the Browns last season. He lost a total of 14 yards on those carries while scoring just two touchdowns.
Losing about two-and-a-half feet per carry when your team is counting on you to punch in a touchdown is not good, of course. And while his numbers were especially awful, Chubb wasn't alone: Leonard Fournette, Saquon Barkley and other workhorse runners struggled to produce short touchdowns last year. That's because big backs can break your heart at the goal line, whether in fantasy football or the real thing.
