In other words, if the other teams knew that a player would be great, they'd never let that player slide to the teens or 20s so it's impossible for Ainge to have great drafts, despite the fact that he's drafting great players. That's one of the most convoluted arguments I've seen on celticsblog, and I've seen a lot of posts. I'm not sure if this was your original point or if you switched to it to defend your evaluation of the Rondo/Jefferson/Perkins picks, but it doesn't make sense.
Also, it would have been a lot simpler if you'd articulated earlier on that your criteria for a great drafter is someone who picks players that, by the nature of the draft, won't be available when he chooses. I wouldn't have bothered to argue how great a player Rondo was for his position in the draft because how good the players Danny picked turned out to be has little to do with your evaluation of his drafting.
Right. I'm trying, with mixed success, I hope, to fend off several competing arguments about how to evaluate how good a pick was. It's making for several parallel arguments that are admittedly not easy to follow or make coherent sense of, since they each start from a different premise. Perhaps "how you you evaluate draft picks" should have come before "is Danny a good drafter"?
So, your question of how can you draft great players without being a great drafter, I would respond by saying that nobody can be evaluated based on only one pick that worked out, but on overall record. There's Rondo, but also GG and Banks...big hits offset by complete busts.
SO, Was Rondo such an incredibly awesome, out of nowhere, great players never come at that level of the draft, Danny MUST have seen something others didn't-type pick that it make up for GG and Banks?
I've tried to fend these different arguments in appropriately different ways.
The one, by pointing out that the odds of finding a star at that level aren't as long as some suggested, listing several players taken around there in recent years that are stars, champions, starters, all-stars, or just really good. I get the response that Rondo is better than the other players right now, which was not my point.
To the other, I point out very valid reasons that Rondo was not in fact taken higher by other teams at the time, and get generally poo-poo'd on with the idea that he should have been, which seems to me to be a denial of the level or risk involved with taking him. I suggested playing with a great team helped emphasize his strenghts and hide his weakness, and someone wrote that he'd still be an allstar if he played for Minny, which I strongly disagree with.
SO it's no wonder things seem a little fragmented and inconsistent. I stand by the objective criteria in the OP, with the modification that the second round is much harder to predict than I initially figured. My criteria for what to expect from middle 10 picks, 11-20ish, is generally consistent with what 82games has on their site for what to expect from these picks, by the way, but still that seems to be where the most disagreement is about what to expect. That I didn't allow for some busts and should have is the only major deviation I'd make there from the OP, based on the many good perspectives I've read here.
