Seems pretty serious about the transition, I imagine he's tired of run left, run right, incomplete pass and either punt or field goal. Its time to change and go back to afc roots and have an exciting offense, that is what this franchise was built to do.
The mere fact that he wanted to interview Callahan tells me we are going WCO.. lots of presnap formations and shift, lots of short to intermediate passing.. passing to set up the run..
