The bubble burst on Cody Zeller, but his stock has fallen too low in my estimation. Expectations were built on him being able to hold down the center position at the next level, which was never in the cards.
In the increasingly quick defenses teams are putting on the floor (to counter small-ball offense), Zeller could excel. He would have no trouble defending PFs, with the ability to switch onto guards and SFs on the perimeter. He could be a crucial piece in making the Wizard's defense terrifyingly athletic.
On offense, he's very skilled. Though he may not be a banger inside, that's not what NBA teams need to be effective. I see him with offensive potential in the mold of Chris Bosh, who isn't known for his physicality (they weigh about the same now). He did not showcase the ability to shoot the ball from the outside in college, but can show potential there in team workouts, then I don't think it would be crazy to draft him at #3.
