Cavs are by far the biggest loser. No has fallen (at least on paper) more than them. I am actually pretty confused when I hear people talking about them as a 40-win or borderline playoff team. I can't see how they'll win 30.
No Lebron
No Shaq
Z is probably gone (to Miami)
Hickson has some talent, but young
The rest are role players(Jamison, Mo, West, Andy, Moon, Gibson, Parker) who can't lead a team.
How do they win 40?
I think 25 is more like it -- even if they pick up Big Al.
