You just illustrated the point I'm making. Most of those deals are crap and not much better (if at all) than we could get hanging on to our pick and using cap space plus a trade or two for the right pieces.
Hell, if the packages you outlined are the going rates for mediocre vets let's just trade ours for top 10 picks.
Everyone of them involved players that would patch or address at least one of our weaknesses.
The problem with draft picks is the same overoptimism effect that casinos count on to steal your money makes everybody stupid on draft night. History says you have about a 50/50 shot there with a #6 pick, and its only a single player who might not be ready immediately.
Here are the last 35 years of #6 picks (sorted from first to last by career PPG):
Damian Lillard 246gms 20.2pts

I mean, there are some scattered good players in there but in 35 years the Portland Trailblazers are the only team to have ever drafted legitimate stars out of the position. Many of the other productive players were considered dubious assets -- Mercer, Reeves, Kaman, Woolridge, Walker. There were several more severely curtailed by injury -- Roy, Gallinari, Gugliotta. And then its a long list of roleplayers, spot starters, and flat out flops and scrubs.
This is supposed to be a good draft, there are players of interest here. But sticking our nose up like our #6 pick is just way WAY too valuable to EVER give up for a mere couple of solid vets is ignoring history. You take a guy like Avery Bradley and he's solidly middle of the pack of 6th pick results. Looks like Olynk might be too. Or Kidd Gilchrist. Or a lot of guys. There have been 4 career 15+ppg scorers drafted at the #6 spot in the last 35 years, and 2 of those 4 were known as selfish chuckers, and 1 of the remaining 2 disintegrated physically after a few years. Its hardly an unassailable level of play.
