Danny has been exceptionally good with 2nd rd picks, and pretty mediocre with 1sts. Giddens is on that second list.
How so?
He "hit" on Gomes, although as I noted earlier my view of Gomes is as a fringe-player on a good team. On a bad team he puts up numbers, but on the Celtics of today he's a ninth-man.
He "hit" on BBD, who IS a ninth-man on the current Celtics. I don't think too many people view him as a legit NBA starter, as evidenced by the deafening silence when he was a free agent this summer. Besides, if you want to give Danny a bit of a pass on Giddens because he was a very late 1st rounder, you need to take away a little credit for BBD because he was nearly a first rounder.
He "hit" on Powe, who's having the same injury problems that kept him out of the first round to begin with.
Who else that Danny drafted in the second round is still even in the league?
Best-case, that's three useable NBA players, but it's not like they're a Gilbert Arenas or Monta Ellis in there.
How many GMs have a similar track record in the second round? R.C. Buford, certainly. Who else has added as many rotation players in the second round as Danny? My guess is the list is very small.
Not sure about GMs, but just for fun, here are some second round "hits" since 2003 by different teams (and I am counting them on their overall performance in the NBA, not just the team that drafted them. I have also done my best to list guys on the team that they ended up playing on during their rookie season, but I am not 100% positive of all of them. So if anyone wants to correct it if players did not play for the teams that drafted them, feel free):
Cleveland: Jason Kapono (2003), Anderson Varajao (2004), Daniel Gibson (2006)
Lakers: Luke Walton (2003), Ronny Turiaf (2005), Von Wafer (2005), Marc Gasol (2007)
Washington: Steve Blake (2003), Andray Blatche (2005), Dominic McGuire (2007)
Seattle/OKC: Willie Green (2003), Kyle Weaver (2008)
Orlando: Zaur Pachulia (2003), Travis Diener (2005), Marcin Gortat (2005 from Phoenix)
Milwaukee: Keith Bogans (2003), Ersan Ilyasova (2005), Ramon Sessions (2007), Mbah ah Moute (2008)
Chicago: Matt Bonner (2003), Chris Duhon (2004), Aaron Gray (2007)
Utah: Mo Williams (2003), CJ Miles (2005), Paul Millsap (2006)
Indiana: James Jones (2003)
New Jersey: Kyle Korver (2003), Chris Douglas-Roberts (2008)
Atlanta: Royal Ivey (2004)
New York: Trevor Ariza (2004)
New Orleans: Brandon Bass (2005)
Golden State: Monta Ellis (2005)
Philly: Louis Williams (2005)
Celtics: Ryan Gomes (2005), Leon Powe (2006), Glen Davis (2007)
Detroit: Amir Johnson (2005)
Minnesota: Craig Smith (2006)
Charlotte: Ryan Hollins (2006)
Houston: Carl Landry (2007 from Seattle)
Miami: Mario Chalmers (2008)
Clippers: Deandre Jordan (2008)
So looking at this list, since Ainge has been here, I would put the C's near the top at second round drafting along with the Lakers, the Bullets, the Cavs (they also drafted Boozer the year right before I started this list from), the Magic (who would probably run away with this, if they hadn't traded away Andy), Milwaukee, Chicago, and Utah.
I think this list helps to demonstrate that there really have been a lot of good draft picks in the second round, and there are some other teams that seem to have a knack for finding them.
Some other interesting things is that the Spurs really haven't done a lot in the second round. Most of their damage has been at the end of the first round. The same thing is the case with the Knicks, who other than Ariza, have not really had a second round keeper. However, they have "reached" for several players in the first round, who were projected as second round talent (Chandler, Lee, Robinson), and ended up being very good.
