Who's supposed to be in charge of the team, the coaches or players? Cook never should have been allowed to try to be point guard and do some of the things he was trying to do. That's on the coaches no doubt.
Fran can’t win. He gets beaten up for being a “player’s coach” and allowing Cook freedom and then we hear he is suppressing someone like Moss and not giving him a long enough leash. Which is it? I agree he shouldn’t have allowed Cook to effectively work on his game and NBA skills to the detriment of the team but I imagine he was hopeful that Cook could put it together and be the “man” as him and Cook likely envisioned 3 years ago but Cook couldn’t put it all together. And like was mentioned above, it seems like when he realized he couldn’t do those things and Fran let him know that, his effort went down.
