I'm not a GM, but I need a player that can add value without needing the ball.....Okafor requires the ball to be effective.
I'd take Cauley-Stein over Okafor each and every year because he's faster, quicker, can guard three positions and can get offensive rebounds, while scoring on putbacks. I'm not saying Cauley-Stein is Joakim Noah, but I think he's a Noah 2.0 type of player.
If you are going to draft a big, get someone that can play both ends of the court....if you are going to be a potential liability on defense AND shoot 60% from the line, can't I get that from someone that is faster, quicker and more likely to switch out and guard Draymon Green or Danny Green or Rudy Gay, while also being able to pester a Marc Gasol or Lamarcus Aldridge on defense?? Does anyone see Okafor projecting to be able to guard anyone not named Andrew Bogut??
