Rudy isn't the extrovert that Donovan is. I wouldn't expect those things. Mitchell knows he's loved here, and he's been given the keys to the franchise. Utah has helped him become an All Star and a brand in the league.
I see where Rudy is coming from, if the organization is giving slack to guys like Conley and Mitchell in some situations and not doing the same for Rudy. However, there's a positive way to handle it and a bad way to handle it.
Maybe the solution is to trade Mike Conley, move Mitchell to the 1, and bring in another guard or wing who, along with Ingles, can get Rudy the ball more when he's in an advantageous position.
