Please. Spend 10 minutes reading some archive posts on a Cavs blog (for example
http://www.cavstheblog.com/?p=4027 ), and you'll get a different perspective on Colangelo. The short story is that the Cavs had GM's who couldn't get any better support for LeBron than the likes of Larry Hughes, Mo Williams and Antawn "worst defender in the league" Jamison. Theystruck out repeatedly in the draft and brought in bad free agents. Danny Ferry's useful contribution was to eventually find SOME decent role-players who complemented LeBron. Not enough, and too late. The Cavs were an amazing team because LeBron was the best player in the league.
Doesn't it tell you something that Raptors cast-offs Anthony Parker, Jamario Moon, and Joey graham were all playing serious minutes in LeBron's last year as a Cavalier?
Most fans have blinders on. They pay closest attention to what their team does, and as a consequence their opinion of their GM is usually very black or white: he's an idiot because the team sucks, or he's a genius because it's been doing well. But it doesn't take TOO much work to pick out the GM's that have really objectively struck out: Isaiah Thomas is the most obvious recent one (thank god he lost the ownership battle in Toronto, eh?), Kahn is a pretty promising candidate (Johnny Flynn 6th overall!) but Danny Ferry is a pretty safe pick (edit: or else Jim Paxson, his predecessor). If you can't win a championship with 6 years of LeBron James, you probably shouldn't be an NBA GM.
So anyway, yes, Toronto was helped in its rebuilding project by sucking more and therefore having higher draft picks. But the contracts Colangelo had around Bosh were also better, plus Colangelo is clearly very skilled in unloading contracts he doesn't want anymore. Colangelo as of last summer did not have a lineup full of youth: he has CREATED that, and he was able to because the contracts he already had didn't tie his hands, and because he made deals happen. Take a look at Cleveland's lineup. It ain't pretty, and no, that's NOT just because we were a worse team.
