to mean the stretch 5 is a spot he'll play once in a while when they want to do something different from their normal game where Keita and Fouss play most of the minutes at the low post.
Doubt there would be consideration of playing either Keba or Fouss at the 4.
I don't believe Boskovic will play the majority of his minutes at the low post in the absence of injury to KK or Fouss. But it's nice to have him available to do so if necessary.
This team is now deep at Center and at Point Guard.
The other three positions are pretty fungible/positionless and we've got gobs of talent there also.
