I think it's hogwash.
No person in their right mind is going to be sabotage their chances at winning a Super Bowl in the Super Bowl. And they had a fiasco with their starting center right before the Super Bowl as well.
People forget how great the 2002 Bucs defense was. Their QB rating allowed on defense?
I think Callahan probably just out-smarted himself and it probably didn't make much of a difference anyway.
