All of the above guesswork is unnecessary. IMO, Pop will divide minutes for the frontcourt reserves based on matchups, not a steady rotation. Bonner's minutes will be limited when we need to slow down scoring in the paint with Theo, and Bonner will come in when we need to spread the floor with perimiter shooting. As for Ian and Haislip, they will likely come in when he can do a better job than either of these two, or otherwise during garbage time.
If you want to break down minutes, your going to need to look at the matchups that we are going to see each game.
