What about Roscoe Smith? If Green is moved (fingers crossed), he'd be another 3 with good size who can rebound. I'd rather have him than Chris Johnson.
Isn't James already like 28-29 or something? I'd rather have Oden, but if we're talking strictly summer league, what about Alex Oriakhi? Sure, he's 6'9", but he has a 7'3" wingspan, I believe, and he's certainly used to the role. Unfortunately, our frontcourt would continue to be the least intimidating in basketball, haha
We can fix that in next year's draft, anyway.
