I don't think Chandler will work in the triangle offense, he has no post game whatsoever. With Tyson gone, we have a big hole in the middle to fill. Aldrich has shown some flashes, but his post game is still raw and he isn't a starter. Stat has improved his post game but he will always be a liabilty on defense and his durabilty is always a question mark. Tyler is also still a work in progress and looked his best after getting heavy minutes in the D league, but again a project, not a starter.
I can see Bargnani being used as sort of a poor man's Pau Gasol. He spreads the floor and is a decent passer. He also has size at 7'-0", but not a center in the trangle.
This really doesn't leave alot of options. I am not sure what Bynum's relationship with Phil was, or if he even has anything left but it could be a low risk high reward move at the vet minimum. Between Fisher and Phil, maybe they can get this kid refocussed on basketball. He is still only 26 and should be in his prime.
Also, Steve Blake is another name I think we might see this summer as Phil rebuilds his triangle offense
