As already discussed, you cannot just look at the 6th picks historically. You have to look at the players who were available for the 6th selection whether they were selected there or not. Players like Curry, Dirk, Paul, etc. change the conversation dramatically if you consider who was available at 6 in the past 20 years. This is especially true if you are going to through out percentages.
You absolutely can, those guys may have all been available at 6, but obviously the teams who drafted at 6 passed on those players because they thought other guys had more talent.
That's the problem with the lottery - not knowing which draft position you'll get isn't the only risk. The other risk is not knowing how good any one of those players will become.
We may look at the draft right now and say "that guy looks like a great pick at #6, he'll be a star". But then that guy might end up a good bench player at best, while the guy the next team takes at #7 or #8 may end up that elite superstar we WISH we'd chosen.
The draft is a massive gamble. Miami wanted to draft Darko Milicic in 03' because he was considered the safe choice - everybody believed that with his size and talent, he was going to be the third best player in the draft after Lebron and Melo. But Darko was taken at #2 by Detroit and Melo got drafted #3 by Denver, so Riley was stuck in a very tough jam trying to pick between Dwyane Wade and Chris Kaman. Apparently everybody in the business was telling him to pick Kaman (he looked more skilled to them, and they needed a big man) but Riley had a good feeling about Wade and drafted him on gut feeling. In the end Wade was arguably the second best player in that draft behind Lebron, and Milicic became a complete bust - nobody expected that.
The same was true in the 2002 draft - many people expected Thomas Robinson to get drafted top 3 for his incredibly physical talent and perceived upside. People thought he'd be a star. He ended up going 5th and so far hasn't become anybody...while Lillard, Barnes and Drummond (who were all taken after him) have all been far superior players.
That's what happens in the draft. There are ALWAYS guys who look like sure-fire stars who end up becoming bums...and there's always one or two guys who look like they won't work out, who end up becoming nice players.
The top 3 or 4 positions are usually a strong bet, because there's usually 3 or 4 guys in the draft who are pretty low risk choices - but once you go past that top 4, you typically get stuck with a decision to make...do you go for the safe choice, or take a gamble on upside? If you take a safe choice you often end up with a guy who ends up a solid starter, but who never becomes much more. If you take the potential option you often end up with a bust who never really sees his potential.
So you can go off historic results because these are statistics, and statistics are what they are for a reason. Look up the stats over the past 20 years for the #1, #2, #3 and #4 picks. I'm sure you'll find the rate of success is significantly higher than 4/20.
Also, citing Love last year is not relevant. He was in a contract year and prepared to walk for no return. Minny got a fantastic return considering the circumstances. I would compare it to Rondo this year. Everyone was upset at the return Danny got for Rondo. His blow up in Dallas aside, it was the best we could get for a player who would be a FA at the year's end anyway.
Not really...the Wolves made it pretty clear that they had no interest in letting Love go for nothing. It took the #1 pick in the draft (Wiggins - a guy who was being hailed as the next big star) and other assets to make the deal happen. We were offering pretty solid assets from what I read, and the Wolves had little interest.
When we got KG, what did it take? Al Jefferson (young talent, a little better than Sully), Ryan Gomes (nobody), Gerald Green (Nobody), Theo Ratliff (getting toward the end of his career), Sebastian Telfair (nobody), and two first round picks. That's not really much more talent going out then Sully + Bradley + 3 firsts when you think about it, and KG was a former MVP and a top 3 player in the NBA at that time. KG in those days was the equivalent of a Lebron / Durant caliber player today - the type of guys most people think of as being untradable.
What about the Ray Allen trade? Boston got Ray Allen in return for Delonte West, Wally Szcerbiak and a #5 pick (which became Jeff Green). Ray Allen averaged 26 / 4.5 / 4 the year prior to that for the Sonics and was a bonafide superstar (coming off 10 straight seasons averaging > 20 PPG). Ray Allen was James Harden / Steph Curry good in those days...while Delonte West and Wally Szcerbiak were (at best) on par with Avery Bradley and Jared Sullinger in terms of talent.
Remember Jeff Green was averaging was a 27 year old with great size (6'9") and elite athleticism for the SF spot, and he was averaging just under 18 PPG when we traded him to Memphis. He was on a decent contract too. All we got in return for him was a single protected first round pick, and an over-the-hill Tayshaun Prince. Note also that about 15 out of the past 20 #6 picks never became as good as Jeff Green.
I think you're dramatically overvaluing their #6 pick, and dramatically undervaluing our assets. Even a guy like Greg Monroe is not good enough to justify giving up that many assets, and he's a 24 year old putting up 16 and 10. Greg Monroe is worth a lot more than a #6 pick - if Detroit offered him for our #6 last year, you can bet your cookies Ainge would have said yes in a heartbeat.
If I'm Danny I would expect a top 25 player in return for this kind of trade, at an absolute minimum. If a team mentioned Jimmy Butler, Greg Monroe or Marc Gasol, then I will probably at least open my ears and see what they have to say. Any less than that and I hang up the phone on the spot.
