There was one thing in your cherry picked reply that I would like to address with a cherry pick of my own
Second part on major trade coup. Well, yes, that is what every team hopes for in every trade. However sometimes those trades do work out in another team's favour. Do you think Hammond/Bucks are not looking at Tobias Harris in Orlando and saying, "WTF?" Colangelo has managed to find those diamond in the rough in Joe Johnson from the Celtics; Colangelo has also managed to find pieces of shit in the flower bed too. I'm not saying this is likely but I'm not ruling out the possibility of it either. The Blue Jays is a bad example because MLB does not have a CBA limiting salaries in trades. I'm not talking about major contracts getting passed from one team to another, I'm talking prospects or guys with talent who have not been in an ideal situation to show it.
Third part on bargains on minimum contracts. More than 2nd round picks can be signed to minimum contracts. Nate Robinson is an example this season. I don't include AA because I don't think he is a bargain (or a diamond in the rough). I think he is what he is: a third string SG who was given more of a role this season than he should have been. Of the 65 games he played this season he only had 13 where he shot more than .500 but 27 games where he shot .333 or less (leaving of course 25 games where he shot between 33.4-49%, 14 of which were less than .400).
I'm not seeing any real reason to see why the Raptors could not "luck" in to a good young player in a bad situation buried on another team's bench, a "cheap" free agent, or a bargain minimum contract. The only reason I see in your post why none of that could happen is because your opinion states it is an impossibility.
