And in answer to your other question, Reality, I think the top big is probably Howard. He's not well developed offensively, but he's active on the glass on both ends of the court, a good defender and shot-blocker.
Duncan's on the down-side of his career, but he deserves mention. And you can say the same about Garnett.
Gasol is still Gasol - 20-10 potential, along with all the soft skills to go into that finesse game.
Bosh is an X-factor guy. Team him with someone like Wade in Miami, and he'll turn into an active, defensive-oriented power-version of Gasol. Think Alonzo Mourning, although not as good of a shot-blocker. But put him on his own team, and you get great numbers, but little impact.
(By the way, I'm calling this now: Bosh to Miami with Wade. The two best defenders from the 2008 Olympic Team, together again. Perfect fit, especially with Riley hiding down there.)
Yao Ming? Somewhat of a disappointment, in some ways. A "wait and see" guy who we've been waiting too long to see on.
Horford? Love this guy. I (wrongly) thought he'd end up being better than Durant. Too bad he's stuck in Atlanta. He'd make a great fit alongside LeBron James in Cleveland or Durant in OKC. Bit of a black hole guy, but a POWER guy. And still young.
Nowitzki? Obviously among the top, but equally obviously not the top one. It's good for a big-man to have a jumper. But it's not good for a big man to have ONLY a jumper. When you think about it, NOWITZKI is missing a lot of big-man skills. He's a poor shot-blocker. He's got no power move AT ALL. His finesse move is a fade-jumper. No jump-hook. Not a good passer out of double-teams. Doesn't throw many turnovers, but that's because he doesn't pass - he just shoots (ala Nick Van Exel). But he's without a doubt the best SHOOTER of all the bigs.
Bynum? Why even mention him? He's a big nobody. Take away a bit of height and bulk and he's Jeff Foster. Were he not a Laker, he wouldn't even get mentioned. Incredibly overrated. LA's version of Kendrick Perkins, except, of course, that Perkins is a solid defender. Someday, somebody is going to pay this guy big bucks. My take? Eddy Curry II.
No mention of David Lee. Not a real candidate, but needs to at least be mentioned.
No mention of Carlos Boozer. Undersized, yes, but he's more than solid, and has more soft skills than most realize. Better defense this year, but that's not saying much. Does merit a mention.
Kaman is okay, but nothing special.
No mention of Amare Stoudemire. He certainly belongs in the discussion. If he had half a brain, he might figure in prominently. Actually, that's an unfair comment. Should have said he needs a brain in proportion to the size of his ego. Just don't know how he'd manage to fit that into a single head. Don't know what he did with the part of the one in his head that he's not using, although, that could explain why Nash blossomed when he went to Phoenix. Nash is a brain-leech!
Probably ought to mention Lopez up in New Jersey. Solid young kid, but we still need to wait and see.
And there's the Big Boatanchor in Cleveland, who is now too much entertainment and not enough game. Still a piece of a championship puzzle, provided he decides he wants to work at it, but too far gone beyond caring. Another casualty of bad work ethic.
My call:
1. Howard
2. Gasol
3. Duncan
4. Garnett
5. Nowitzki
