Their problem isn't Nash being hurt though.
Kobe's 70% maybe. Dwight's maybe 70%. Also, their bench isn't brutal, but it's certainly not used to playing together yet.
Clearly they look to be a team with a lot of talent that's in a transition phase. Once they get healthy, and get it going, they're going to be extremely difficult to beat because not only do they have the Post-Swing-Point trio locked in, they add another strong post presence in Dwight Howard.
However, he's got to pull down more than 8 boards in a game against questionable post talent (Clippers) in order to be effective.
