MacT has the ability to make sweeping changes if he wants to. Horcoff, Smyth, sweep out the coaching staff and hire Ruff. If he's serious about bringing in change, there's plenty of potential big changes out there.
MacT sure has his job cut out for him. I'm sure he will make changes. The question is can he make the right ones? I doubt it... no chance Horcoff is gone. Zero.
