With Kobe out, this LA team is basically like Howard-era Orlando, but with Gasol. They want to kill you on the glass, force-feed Howard (and sometimes Gasol) in the post and are otherwise content to launch threes.
Ultimately I don't think they can beat OKC in 4 out of 7 games. Perkins was made to check Howard, Ibaka can handle Gasol and OKC's perimeter rotation is way too athletic for LA. Steve Blake cannot hang with Westbrook, and when Nash gets back that problem only gets worse. MWP can cause problems for Durant in half-court situations, but not when Durant gets out on the break.
It might be more challenging than most 1-vs-8 matchups (certainly more than Heat-vs-Bucks) but I don't think they can win it unless Metta punches Durant in the throat and takes him out for the season. Which, now that I think about it, may not be so far-fetched.
