I'll ask this...what's the difference between having an H-Back - Hanna - line up in the backfield, and having Connor do it? We havent established either Hanna or Escobar as enough of a threat in the passing game that other teams are going to drastically change their personnel and panic when we bring them in the game, so for the most part, they are just a FB who splits out and takes a defender away. Considering the fact that Hanna is in the backfield all the time, as a lead blocker of sorts, why not just have Connor, who is an absolute hammer, take that role?
You could add Connor and not change a thing about the offense except that you could be more effective running the ball in short yardage situations.
