Jones bulked up over the off season. I forget the amount, but IIRC he gained like 7-8 pounds of muscle mass in hopes he'd absorb hits and avoid injury.
He also carried the ball 23 times and had 27 touches. I cannot fathom McStubborn ever allowing that. Im not saying Jones could handle that over 16 games, but it's still refreshing to see a HC actually willing to RTFB.
