Despite the mid-season trade, the Cavs are still a very good rebounding team. THats the one thing that scares me.
Rebounding in todays NBA is, IMO, very much under-valued. The Cavs do extemely well on both the offensive and defensive end.
They have excellent balance on the offensive end when a shot goes up. They do have the big guys to crash the boards, however, their transition D is top notch. I believe their offensive rebounding in this series will determine the winner.
If i'm Doc Rivers, i completely focus on getting the defensive rebound before we even begin to think about pushing the ball. Oh, and i'd completely expect to see Leon Powe's minutes dwindle in this series, as (1) I dont think he is a good defensive rebounder, and (2) I dont think he is a good team defender. We really will need both of these things in this series. Look for extended minutes from PJ and Big Baby.
LBJ will almost average a triple double for the entire series - given he handles the ball so much. I dont think this is of particular concern, seeing as though i think Joe Smith will be there no.2 scorer.
They do run alot of curls off down screens - especially for Lebron (very Pistonesque). So i think we have to be at our best team defensive wise.
I think they are being under-rated in general by those here on CBlog. I cant believe there are those who think the Hawks posed more problems than the Cavs. Think about it - this cant be true.

I think the way we play team defense leaves us succeptible to good 3-point shooting teams. Whilst the Cavs havent set the NBA on fire with their 3-point shooting, they do have guys who can shoot the rock.
I can see Joe Smith doing a Marvin Williams on us. He will be a guy who will get open 18ft jumpers, and if we are not careful, he will hit a high pct of them.
At the other end, the Cavs are fairly close to the C's in terms of an excellent defensive structure. Whilst they have so-called weak defenders (eg Wally), they play good team D. Our ball movement, and potential mismatches on this end must be exploited. GO at LBJ!
All in all though, the Cavs are the team we had our eye on from the moment the playoffs started. Look for the C's to win in 6.
