I have faced option teams, and what I have notice is that the QB, when running, bends over like he was punched in the gut and running in quicksand. This animation hurts the play from having positive yards. I think I saw a couple of plays where the QB and HB had very nice runs for 10-15 yards, but it's rare.
There is something with the game engine that is not allowing this type of offense to do well. Outside from that, running the ball with my HB alone has been fine, as you can see from my stats. Only the dreaded "HB Glitch" kills a lot of big gain runs from time to time.
Stay away from the Option Playbook if you as me.
