I give the benefit of the doubt because I didn't pay attention to TC around his tenure. But if scaling back cost him, then I know he regrets it. I aslo personally believe that players didn't respect him. I noticed the body language of the players and at times DA attempted to sound like Payton too much.
I remember Keenan Lewis made a statement awhile back (years before Payton stepped down) saying that DA didn't have the right people skills. Maybe there's some truth to that.
