Go back and look at the entire video of his draft. The guy was not happy he was drafted by Buffalo. I also feel he is getting terrible advice by both that assclown brother of his and his handlers.
Dallas needs an RB and make a splash. Cook + 30 and a 5th or so for #12.
Just trade him and move on.
Too many times we create pressure from the outside, only to have Mahomes etal. Step up and either throw or run. The way you beat him is the way NYG used to beat Brady. Take away his pocket and put someone directly in his face.
