Giddens was #30th.
Blaming Ainge on not picking Jimmy Butler, Marc Gasol or DeAndre Jordan is to some degree pretty stupid. Why? Cause if GMs would have known how they develop Ainge wouldnt have had been able to pick them in the first place because they would have been gone allready.
You highlight, IMO, one of Ainge's worst decisions as GM -- he picked Giddens over Jordan, even tho Jordan was clearly the better pick at #30 in the NBA draft.
I'm a staunch Ainge believer, but I screamed at the TV that night, and it bothers me to this day.
I despise retroactively looking at draft picks because hindsight is 20/20 unless you're talking about a top 10 pick - one that MUST produce a contributor. The way I always view the draft is that a GM should select a very good starter/star in the top 5 and a solid starter/contributor between 6 and 12. Between 12 and 20 it's a role player off the bench. After that, it's a crap shoot.
We love to pick on Danny for Fab Melo, but look at the rest of that draft. It was a very weak draft class after Davis, Lillard and Drummond. After Danny took Sully (#18 and 5th in win shares from that class - a helluva pick) there's only two players worth a hoot (Miles Plumblee @ 26 and Draymond Green @ 35). So frankly there wasn't much left to pick from when he took a flier on Melo.
Giddens was a whiff but then again when you're selecting at #30 your choices are limited. There were a number of good picks post-30 in that draft, but that's pretty rare and look at the guys selected around Giddens - starting with MarShon Brooks at 25 there's only like 1 pick in the next 13 (Jimmy Butler) who would up worth a darn. So there are a lot of teams who passed up Jordan.
I think Danny's biggest miss was in '06 when he passed up Rudy Gay to pick up Randy Foye and then moved him and LaFrentz for Ratliff and Telfair. I can't remember if that was purely a cap move or not, but I remember being pretty p---ed at Danny for that one. Of course, that was the same year he got Phoenix to pick RR for us (for $3m), so I think he made up for it.
