Here's the five biggest success stories and cautionary tales from the past six drafts:

Success stories

Kyrie Irving (2011 Draft — 1st overall out of Duke) — Rookie of the Year in his first season. All-Star by his second. Already considered one of the league's best point guards. Turns 21 this month.

John Wall (2010 Draft — 1st overall out of Kentucky) — Second behind Blake Griffin in Rookie of the Year voting. Inconsistent and injury-prone early in his career, but lightning quick and dynamic when on the court. Career averages of 16.0 points and 8.1 assists. Widely considered a future All-Star.

Eric Bledsoe (2010 Draft — 18th overall out of Kentucky) — Backed up John Wall at Kentucky. Backs up Chris Paul now. But widely considered a future starter and potential star. Averages 9.4 points and 3.4 assists in only 21 minutes per game.

Derrick Rose (2008 Draft — 1st overall out of Memphis) — Immediately turned around the Chicago Bulls franchise. Rookie of the Year. Won MVP his third season. Career averages of 21 points and 6.8 assists.

Kevin Durant (2007 Draft — 2nd overall out of Texas) — Three-time scoring champ. Four-time All-Star. Averaging 28.6 points, 7.7 rebounds and 4.6 assists this year. Twenty-four years old. Decent player.
