Kyrie Irving and to a lesser extent Tristan Thompson are great examples of why selling off picks because a draft is going to be "weak" is a really, really dumb idea. How strong a draft is usually ends up being a matter of how players develop, not what their talent level is when they are drafted.
The 2010 draft was supposedly STACKED and so far it has produced mixed results. The 2009 draft, on the other hand, was supposedly super weak and has turned out quite a few quality players.
The 2011 draft was supposed to be epically weak due to the impending lockout, and Kyrie Irving was supposedly a weak #1 overall.
Yet here we are and Irving is considered the next great point guard, maybe the next great player period. Crazy.
Meanwhile, John Wall (2010) and Anthony Davis (2012), the top guys from "stacked" drafts, appear to be quality players. But neither has really shown franchise-altering, dominant ability yet.
