Joel Thomas is back as RB coach

We are just curious what kind of scheme he wants to run so we can have some fun speculating on what coaches and/or players might fit his scheme best.
What if it is a new scheme? How would any of us know it. There in lies the issue. Some will start speculating that this or that player doesn't fit a perceived scheme and start complaining/whining even before the season has begun about how they don't like a certain choice. It just gets tiresome.
