He wants things done his way and won't change. Yesterday's pre game interview where they spoke to Shanahan about his competitive nature and desire to beat LaFleur so bad at ANYTHING was telling. Shanahan said he was throwing up and he had to go to him about chilling out.
McVay is acting like Martz now. My scheme, my way. Doesn't matter if the OL isn't good or the QB has pins in his hand.
Hoping and praying he gets some good advice, etc. as he gets older. Otherwise, he is your classic burnout victim.....changes QB's, RB's, schemes, etc. in a quest for perfection on his terms.
