No, not at all, people have to remember No-win, and Dingle Berry spent a lot of time and effort to turn what was once a sports car in to a bull dozer, they never really got that far, more like a snow plow. Anyway, you can change a few players this season, you can talk about a new mind set, but these things take time. It will be a while before this teams plays fast on offense, and executes well, JH was VERY conservative, because he knows this teams limitations, he is trying to build confidence, and raise those limitations.
His Stanford teams were strong running teams, Toby Gerhart was the back bone of what he did there. Give it time Frank will learn to run more zone or he will get less touches, Alex will get more practice, and slowly be let off the chain, this team will improve, but I think JH doesn't just want to rebuild, he knows how bad the NFC west is, and knows if he is conservative early and gets a few wins now, when this team is ready go, he just might have a shot at the play offs.
