I share many of the concerns about Cousins that have been expressed elsewhere, but I also just had a thought:

How many current NBA centers would you rather have them Cousins?

Without question group (of one):  Dwight Howard

Only because they're a known quantity not because upside is greater:  Lopez and Bynum (can't stay healthy)

Solid centers, but would you trade Cousins for them?:  Marc Gasol, Kaman, Bogut (nasty injury), Yao (durability concerns), Oden (can't stay healthy), Noah (limited offensively), David Lee (solid, but a product of D'Antoni system?), Hoford (undersized), Hibbert, Bargnani, Okafor, Thabeet (I'd certainly rather have Cousins than the #2 from last year).

Great, but past their prime:  Duncan, Shaq, Jermaine O'Neal, Rasheed.

Assuming he measures out at 6'11" with the reported 7'6" wingspan, Cousins may be the only player in the draft that has top 5 value at his position.   Are Turner and Favors top 5 value at their position?  I love Wall, but not sure Paul, Deron, Rondo, Rose, or Evans gets traded for him.  And there are certainly a handful of other very solid PGs (Westbrook, Curry, Jennings, Jameer etc).  There are certainly 5-10 SFs with greater value than Wes Johnson.
