Well, we have our PG and C studs, our young gun at SG, and our wing defender with length, athleticism, and range at SF.  Now we just need a young PF to bang down low, rebound, defend in the post, score a few points efficiently, and be our enforcer.  In other words, we need a guy to do the Perk work.  
So, New Orleans is happy to select Dejuan Blair.  Maybe a little high, but we love his efficiency, hardnosed play, and ability to grow with the team. He'll be a good high-level role player for years to come.
