Certainly, I think Gasol is gone. Bynum going nowhere, and the Lakers is not going to go after Howard. If possible, they would wait for his contract to expire after next season, if Orlando does not trade him first(which is what I think they will do mid-season).
Lakers needs to replace Pau, if they let him go...with who I don't know at this time, and also needs some supporting bench players. The Lakers can find a replacement for Pau either from Portland, Utah, Toronto(Amir), or Memphis(Arthur). Peace will be back, I think for another season. Lakers have a 3-4 year window with Kobe...so look for the Lakers to spend big.
If Boston wish to implode the team, I can see the Lakers going for Garnett to either come off the bench, with spotted starts or start at the 2 as a replacement for Pau. Primarily, I would like to see Rondo(only one I really want from Boston, but may cost) as the starting point, and Sessions come off the bench. However, there are other lesser name starting point that may be cheaper and yet still effective. Or they can just try to groom Session.
I can see Barnes, Murphy, Blake, and Morris gone as well.
