Yes, McCarthy said he wants tor run more. But BigMac didn't run the ball in Green Bay.
It was a rarity for McCarthy’s backs to even pass the 250 carry threshold during his time in Green Bay. Only Ahman Green (266) in 2006, Grant (282) in 2009, and Eddie Lacy (284) in 2013 accomplished the feat. That’s just four times in 13 seasons that McCarthy fed the lead RB in his offense.
McCarthy’s backs also only ran for 1,000 yard in five of his 13 seasons in charge.
Doesn't mean he can't change, but likely he's going to RBBC, rather than relying on a bell cow.
Also he doesn't have a Favre or Rodgers at QB. So running will help the offense control the clock and shorten the game where he doesn't have to outscore the other team.
