I'll help out until he gets a chance to expand (if he can). This was spoken about at one of the ISD lunches in January, from 2 people with contacts deep inside the program. A lot of the players did not like Diaco. This shocked me because I thought the players loved him. Not so, according to 2 people I trust. The feeling was he was selfish and only looking out for his next job.
And then 2 weeks ago I talked to another guy who knows several players, and he said the same thing. His exact words: "Diaco was friggin' psycho. Like straight up psycho." Said the same thing about a lot of the players nit liking him. and believe me, this guy would know. He also told me that the players love BVG so far, as Burning River eluded to.
And Sean Mele at ISD played for BVG and he's told some phenomenal stories about BVG; he predicted when BVG was hired that the players would love him.
