The thesis here is that LA would be in tank/rebuild mode, since they have very little opportunity to build a contender around Kobe at this point.
In terms of all the guards on LA's roster, honestly its irrelevent. In rebuilding mode they'd basically be looking for bodies back- young cheap talent. Unfortunately all the young cheap talent we could add to a deal are guards- Larkin, Shumpert, Early, Hardaway Jr. are our best pieces and 3 of those guys are guards.
Its a pipe dream, but IMO it makes a lot more sense than Melo signing in LA. Kobe has a no-trade clause. He has to determine whether finishing out (and not winning much) in LA matters to him more than finishing his career with a chance to potentially contend. He is a believer in Phil, so it would seem that this would be a destination where he would follow.
IF somehow we could make it happen, it would certainly increase our likelihood of getting someone like Pau. Again, a pipe dream, but not a 0% possibility with Phil Jax here.
