I think the bench will be stepping up big time, and for an obvious and simple reason. They've finally gotten ample practice this week.
The problems with the bench have not been talent-related. They've had to do with clock-management, knowledge of offensive options, and pure fatigue/injury.
For Baby and Delonte, the week-long rest will prove crucially beneficial. For Jeff Green in particular, a week of practice with Delonte and Baby will enhance his decision-making. He'll know when to initiate his own offense, and when to step into the background. Once that happens, the shot clock violation problem will mostly disappear. Get Shaq back eventually, and you've also got a rebounding/defending presence in JO. Watch for this bench to gradually step things up. I'm sure of it.
