As far as what Doc will do, I think he'll start the year with JO in the starting lineup. However, I have an idea things may change after Shaq demonstrates a more effective ability to work with the other starters. I guess it's nice to conjecture, but I really think we need to see how this team develops chemistry-wise before we can really make these calls.
This team has changed in many ways over the off-season, and I don't think anyone really has a clue as to how these new rotations/combinations are going to meld. It's going to be a heckuva lot of fun to watch things develop, but I think it's way too early to make these kinds of assumptions. We'll see soon enough.
