The way i see it, the Celtics have two options: Plan on the lockout and just run the same team out there for the next 2 years (with one of those likely being a lockout). You'll sell tickets, wander through the regular seasons, and try to make some noise in the playoffs. But the window of a championship is probably closed.
or blow it up. My blow-it-up scenario is admittedly wishful thinking that requires many things to fall into place.
1) Convince Lebron to sign in Chicago. We'll trade Kevin Garnett to Chicago for Luol Deng and Hinrich. I believe that saves Chi some money too to help sign Lebron.
Chicago would have a core of: Rose, Whomever, Lebron, Garnett, and Noah. With Tom Thibs coaching.
2) Tell Pierce he needs to either Opt out, or we're trading him to the Wolves for Jefferson and Gomes. The T-wolves are looking to rebuild and getting rid of Jefferson and Gomes contracts while reloading with all their draft picks makes sense for them. The suffer through Pierce's deal for a year, or could turn around and trade him for parts, or sign and trade him at the end of his contract.
Boston would then have: Rondo, Hinrich, Deng, Jefferson, Perk with Big Baby and Gomes off the bench.
Boston would also still have Ray Allen's rights (keep him or sign and trade him) and the likely retirement contract of Rasheed Wallace. Both of those are very valuable to flesh out the roster. I'd probably keep Ray for reasonable dollars, and try to move Wallace's contract. But if we're looking to build for the future, moving Ray for younger legs is probably the way to go.
