Shaq is not going back to LA.
First of all, his contract is enormous and it would take a package of players from LA to get him. LA would lose their depth. I don't see that happening. What's Shaq going to add to them? Size? They already size and Odom is more versatile in that he can play a couple of different positions if need be. They'd be losing some roster flexibility.
Second of all, why would PHX trade Shaq within their own conference? Phoenix is still a playoff team in the West and why would they go out and trade Shaq for a bunch of role players? Does Kerr really think a trade with LA will make his team better? I don't see it.
Shaq makes 20 mill this year and next. Odom makes about 12 mill and luke walton makes about 5. If you give 3 million dollar in cash you get shaq.
Phoenix i been reading is said to think about dismantling their team while staying in a close hunt to make the playoffs. Rumors are surfacing that nash could be traded to Toronto for calderon, staudamire to new york knicks for david lee.
Shaq honestly is not working well with the phoenix system, nothing really cohesive playing with nash nor staudamire either.
Phoenix could be shopping shaq but like you stated maybe not to the lakers. If the lakers though gave them a package of odom, walton and a 1st round pick i doubt they would turn that down since they prob couldn't get a better deal anywhere else.
Lakers have a clog in that sf spot with radmanovich, ariza, walton and odom. Yet they really don't have much depth other than gasol and bynum in the center/pf spot
such trade could work for everyone especially the lakers who can come closer to securing the ring
