I've often thought the same thing. Public statements about wanting him to run more were simply to keep the opposing team thinking he might.
You may be right, but I really don't think so. I think Butch and Coach Jake really wanted him to keep the ball more on the read, even if just a couple times per game. I don't see that saying you want your QB to run more is going to effect the gameplanning of opponent's DCs, but having a QB actually keep the ball on a few plays will begin to cause a bit of hesitation among the opponent's LBs and safeties as they actually have to account for the QB possibly keeping the ball. And this offense is going to be much more effective if the QB will keep the ball some.
