If they bring Tomic over, a three big rotation of Gobert/Favors/Tomic would work well, with Booker being around to match-up when an opposing team goes really small at PF. But in that case, you might as well have someone with more offensive game playing that spot.

Ingles, Millsap, and Booker would be really good as the 12th, 11th, and 10th guys on the bench. It is amazing what Utah has done since the all-star break with those 3 all playing significant minutes.
