I would barely lean AD-LeBron a slightly better duo overall but I think the Clippers are stronger top to bottom because the Lakers have so many question marks in terms of health, fit, and rotations. First, I think Rondo and LeBron should barely be on the floor together so that starting 5 to me is not ideal at all. I'd start LeBron at PG, two best small defenders with him (maybe Green and KCP, possibly Cook or Caruso to defend PGs), AD at 4, and McGee at 5. For a closing lineup against the Clippers in the playoffs, maybe Bradley/KCP/Cook, Green, Kuzma, LBJ, Davis at 5. Rondo and Cousins should lead the second unit. Against say the Sixers if they get that far, I might switch a closing lineup to KCP/Green/LBJ/AD/Cousins to match up perhaps with Horford/Embiid. Way too early to know anything though I have no clue how good Bradley is anymore, how well Cook or Caruso can play, etc. If Bradley still can play as an elite defender on 1s and 2s, I think he will play quite a bit. Cook/Caruso/Green all on paper extremely elite catch and shoot guys (very elite actually but volume issue) but sample size isn't huge enough to count on with a few of them. If Cousins is actually closer to the player he was two years ago, maybe at that point you actually tweak things as you can't count on that at all.
I like the Clippers depth much better, but their frontline is not ideal and you will see some PG13 at the 4. You are also counting on Shamet a lot and he is quite young and you never know with youth deep in the playoffs when pressure/intensity is way up. Zubac too who I like but very young and can you count on him when it's high stakes pressure as the key big man off the bench. I think the Clippers are correctly the favorite because I think their defense will be suffocating, and I'd peg the Lakers, Sixers, Bucks, Rockets as all pretty good contenders if things break right for them.
