I'm not a Matt C fan at all but unfortunately this is true. When he's on he's on, and I'm all for playing him. The problem lies when he's not on and he continues to take wild shots and uncontrolled drives. His ability to be a great point guard is there but mentally he thinks he's the Jimmer.
Rose needs to start him and evaluate his game for the first 5 minutes. We have seen when he starts hot he continues to be hot, but when he begins to struggle the struggles don't stop. Take him out when he's off and try him again the following game.
We never know which Matt C we will see from game to game. It's his inconsistency that's killing us. We don't know which PG is going to show up.
