I think the skill that makes Ainge a great GM is his drafting ability. Sure, he's picked some guys that haven't panned out, but he's picked alot more winners than losers.
Ainge started in 2003 right?
Since then, this is who the Celtics essentially drafted (I know some players were drafted by other teams, but when they are immediately traded to the C's it as if the C's drafted them, and I'm not including this year because it's too early to tell on those guys ):
Marcus Banks (1st round)
Kendrick Perkins (1st round)
Brandon Hunter (2nd round)
Al Jefferson (1st round)
Delonte West (1st round)
Tony Allen (1st round)
Justin Reed (2nd round)
Gerald Green (1st round)
Ryan Gomes (2nd round)
Rajon Rondo (1st round)
Leon Powe (2nd round)
Gabe Pruitt (2nd round)
Glen Davis (2nd round)
That's 13 players, 7 in the first round, 6 in the second.
11 out of 13 are still in the NBA , 85% success rate
7 out of 7 first rounders still in the NBA, 100% success rate
4 out of 6 second rounders till in the NBA, 67% success rate
I'm not sure the numbers on other GM's, but those appear to be extremely high success rates especially with no lottery picks, and also when lottery picks in that time frame like Mike Sweetney and Luke Jackson aren't even in the NBA. Just think of our lottery picks from past GM's when we drafted guys like Kedrick Brown and Jerome Moiso and it's a complete 180. Can any other GM say his last 7 first round picks are all still in the NBA or that all first round picks in the last 5 years are still in the NBA? (Legitmate question, I don't know, but I doubt many).
The jury is still out on Pruitt but for the sake of argument let's say he fails and is out of the league soon, that would still be a 50% success rate with second round picks (and it's my belief that Gomes, Powe, and Davis could play and contribute to any team in the league, also with the way Bill Walker is looking that success rate is probably about to go higher too). You think any other GM has a 50% success rate of guys drafted in the second round who actually contribute?
I think Ainge is so-so on trades, but sometimes you got to look at the trades leading up to other trades too:
Ainge essentially traded Eric Williams/Tony Battie for Ricky Davis for Wally Szczerbiak for Ray Allen. It seems like he upgraded each time too me. How many GM's have done that?
