option 2: Rondo is traded for a starting center and we start Smart and AB.
I see this as the best route, but our trade options are limited. The one that probably fits the best would be Detroit. Something like...
Rondo
Wallace
1st rd pick 2015 (LAC)
for
Monroe
Jennings
Butler
Jerebko (expiring deal)
1st rd pick 2015
1st rd pick 2017
Rondo would likely re-sign since it's not a small market and he would be alongside Smith.
We would start Smart, allowing him to further gain experience. Monroe would immediately start alongside Sullinger providing better roster balance. His game, particularly his good passing, seems like an excellent fit in Stevens' offense and would give us a trio of good passing bigs along with Olynyk and Sullinger. Jennings value might be able to be rehabilitated like Crawford's was, which could provide a decent return as his contract would be reasonable (8M) and expiring next season. Butler's deal is not expiring either (2 years left), but at only 4.5M it's also easier to potentially trade than Wallace's would. Plus, Butler has a lot more left in the tank than the running on fumes Wallace. We dump Wallace's contract. We move up significantly in the 2015pick swap, likely from the late 20's to mid-teens, and add an extra 1st pick in 2017.
This, however, can't be accomplished until mid-December because of the restrictions of signed players.
