Hollinger offers mostly, pretty reasonable scouting reports, here. I especially like his comments on Jason Collins, illuminating where his value will probably be for the Cs (as well as his limitations).
Some very minor quibbles:
On Kevin Garnett:
In ranking KG just '12th' in defensive rebounding, Hollinger is generously including players who played as little as 500 minutes in the rankings. If you trim it to guys who actually played a more full-time minimum of 1500 minutes, KG was 6th in defensive rebound percentage. Heck, open it up to players with as little as 1000 minutes and he only drops to 7th (Marcus Canby sneaks in then at #2 with his gaudy 32.7%!!).
Otherwise, he's spot on - as long as KG's knees hold up, he is still one of the leagues elite players.
On Jared Sullinger:
I'm not sure how he can on one hand acknowledge how Sully's main offensive contributions are going to be in the post and then close with "Basically, he projects as a better version of Brandon Bass."

?? Totally different players on offense, imho.
On Fab Melo:
Again, on rebounding - sure, Fab's raw 'per game' rebounding total was not overly impressive - just 5.8 per game. But that number completely lacks context. First of all, Fab was playing in the middle of a zone defensive scheme that tended to result in lots of jump shots and long rebounds, away from him. More important, is if you pace-adjust his number, his rebound rate jumps to 9.3 per 40 minutes - which is much more comparable to other big men taken in the draft before and after him. If you further note that Fab was only a 2nd year player (heck, this was only his 6th or 7th year of playing organized basketball at all) and compare his rebound rates to the sophmore numbers of all his peers in this draft, you find that he isn't really a "Poor rebounder for his size." In fact, he looks like he could eventually be a very good rebounder.
Rebounding is not just raw physique. It is a learned skill and upperclassmen tend to rebound a lot better than they did as underclassmen. Fab, imho, is going to be a fine rebounder in the NBA, eventually.
(Of course, under Doc, he'll probably never grab a lot of offensive rebounds!
