I'm wondering if either Okoro or Windler will eventually be moved to guard, partly because it may be a better position for them and partly because of the loss of Kevin Porter Jr. It also may depend on who we get with our (hopefully) top three pick next year. If it's a small forward, or even a power forward with Nance dropping down to the 3, then one or both of them needs to move.
I agree Windler is fine at small forward, especially if he continues to rebound well, play solid defense, and hit 100% of his 3's.
Being a legit 6'6" with a 6'10" wingspan and good mobility definitely allows him to play the 3, but I think his outside shooting and ball-handling could play at the 2 plus his lack of bulk would match up better with those athletic 2's that have been giving us so much trouble (like that guy who dropped 50 on us last week).
As a 2 I could see Windler posting up opposing guards (especially shorter ones) and scoring from the low post since he's ambidextrous. I've seen him make some nice right-handed jump hooks from five feet out when opponents were taking away his left hand.
Okoro is an inch shorter than Windler and has 35 pounds on him so I see him staying at the 4 because his strength matches up better against forwards and I don't like his ball-handling or outside shooting. He's also four years younger and if anything is just going to get stronger if that's possible.
