Looking at the drafts between 1990 and 2010, the #2 pick has resulted in an all-star 42.9% of the time, and a starter 81.0% (started over half the games they played).
That means 19.0% of the drafts, the #2 pick did not even result in a starter quality player.
Some past #2 picks:
2010: Evan Turner ("starter". Has barely started over half his games.)
2009: Hasheem Thabeet (not a starter)
2008: Michael Beasley (not a starter)
2007: Kevin Durant (All-Star)
2006: LaMarcus Aldridge (All-Star)
2005: Marvin Williams (Starter)
2004: Emeka Okafor (Starter)
2003: Darko Milicic (not a starter)
2002: Jay Williams (starter)
2001: Tyson Chandler (All-Star)
2000: Stromile Swift (not a starter)
CJ is already playing at an all-star level in my opinion (although not yet an all-star). On top of that, he's a quality teammate. I'm sticking with CJ.
