I say no. I posted this in a different thread, but felt it might be an interesting discussion to have in its own thread.
Here is the entirety of the moves he made

Draft Picks
Billups
Mercer
B. Pepper
Pierce
Moiso
All in all, Pitino left the team in much better shape then when he took over. He drafted Pierce, he brought in Battie, Anderson, kept Walker, traded and then brought back Williams, etc. (who would all be key members of the early 2000 playoff runs). He also had the Denver pick with the Celtics choice, he had what would be the 21st pick in 2001, and every single first going forward for the Celtics.
And frankly a lot of the bad moves he made, he was able to correct, i.e. trading Knight for Battie, getting the extra draft picks to help with the loss of the one he gave up for Potapenko, etc. Even the Billups trade wasn't that bad when you look at the entirety of the circumstances (Billups took a long time to develop and Anderson was pretty darn good for the Celtics for a few years). He certainly missed on Moiso, but that was a pretty weak draft overall. If Wallace, who Pitino brought in unfortunately, wasn't a complete and utter idiot (I mean seriously taking the Denver pick in 2001 which was 11 when you already had 10 and 21 - terrible, and Forte was just an awful pick), than I think people would look a bit differently at the Pitino era.
Also, I believe that because Pitino was coaching and serving as the G.M. simultaneously that he made moves and did things he might not have done if he was only in one role. Like the trade of Billups, I think he made that trade because he felt immense pressure to win now and Billups was clearly going to take awhile to develop. I'm not giving him a pass, nor does it really have much to do with my initial premise, but I think the dual roles adversely affected his ability to do either job to the best of his ability (and even with that, I don't think he was nearly as bad as has been made out on this board).
