McCoy acknowledged on Wednesday that the bigger, more power Polk will be handling a significant portion of the short-yardage situations going forward.
"He's not getting all of them, but if it helps the team, that's what I'm going to do," McCoy said via CSN Philly. "There's just some plays on third-and-1 type of situations where I probably wouldn't have gotten it, where I see him kind of hit a guy, drag a guy and get in there. It's hard to be selfish with a player like Polk to use him to do those type of things."
It was just two years ago that McCoy was one of the NFL's most efficient short-yardage backs while leading the league with 17 touchdowns.
As Game Rewind proves, though, McCoy's observation is irrefutable. Polk isn't speedy, but he's been a tackle-breaking machine with the relatively few opportunities he has been given this season.
