My take on not playing GV, Landry and Jimmer is this:
With GV I suspect they are just being careful with him coming back from surgery.
They know what Landry can do plus he is nicked up a little.
Due to the roster depth Jimmer was just not in the rotation for the first game. I think we will see him as preseason rolls on. He is going to have to really impress to get minutes. Unless a trade is made then he may get more minutes.
Also I'm thinking the Coaches are watching to see how guys react to sitting on the bench. Especially a big college star like Jimmer.
