He will never be a STAR.
He has the physical attributes but STARS possess that inner drive that CANNOT be taught. You either have it or you don't. Look at Emmitt, Troy, Irvin or Romo. These players play their hearts out for $1 million or for free. They motivate themselves. That's what it takes to be a STAR.
Bennett will be a teaser because he's got ability but this league is full of people with ability. He'll be decent and play a few years and be gone like many before him. In fact, I think Fasano may last in the league LONGER than Bennett. He may not be a starter but Fasano is a willing blocker, worker who is willing to do everything without someone constantly chewing on his ears.
