Doc does bring up some good points about LA.
1) We've had a harder time with Bynum than Howard. That's largely because Bynum is a better offensive player than Howard, who is still quite mechanical, even at this stage of his career.
2) Nash is no sure thing. First, he's 38 going on 39. People worry about KG, Terry, and Pierce, but Nash makes them look young. Secondly, the last time that Kobe played with a real PG, things didn't go so well (Payton). The difference is that Nash shoots much better than Payton, so even if Nash gets turned into a spot up shooter (what happened to Payton), he'll likely do better at it than Payton.
3) Kobe in the Princeton offense may not work out. As Doc says, I'll believe it when I see it. And if that falters, all sorts of problems could arise, as Nash gets turned into a glorified Eddie House and coaching crumbles as Mike Brown doesn't have the reputation that Phil Jackson does to force it down the team's throat.
We shouldn't sleep on LA, but it's also not like they should be sizing rings yet either.
