Yeah, the teams running out of the flex or other option formations can run it decently. I think that has something to do with them giving it to the back running up the gut in the triple option. The cpu has a harder time screwing up a run up the middle. Teams running option out of the shotgun can't pull it off as well.
The cpu running ability in general is hit or miss. It wants to get to the outside way too much, sometimes running away from huge holes in the middle. It's over use of the juke and hyper active style also get it in trouble.
