New Orleans is very good, especially their top 6 players. They do everything about as well as the Spurs do, if not better, except on defense. They have a better points differential than the Spurs and they rank #2 in 3-pt FG%. Like the Spurs and Detroit, if they score 100+ points, they are almost impossible to beat.
The Jazz are better with the Korver addition. Kirilenko is a top-15 shot-blocker, G-Dub so if they lack one, then they lack a 2nd one.
Deron Williams and Chris Paul are even better this year, by an order of magnitude. Like Baron Davis, they can basically take over games.
The West's Top 10 are the best in memory. It may come down to defense and who's healthy.
