Coach Self and most every other coach I have heard on the subject (I posted links before to several of them) have always indicated that by the time the main portion of the schedule comes, they like to have a rotation of 7-8 players. Of course they will play more than that but the bulk of the rotation will be 7-8. Calipari had a deep bench lasts season and tried the platoon system which did not work well and indicated afterwards that he will never use it again and will go back to the more traditional 7-8 player rotation. So, even with a faster pace, I expect to see Coach Self settle with an 8 player rotation taking the bulk of the minutes.
Now, with the shorter clock, there might be more possessions, although the average time of possession for all Division I is only around 18 seconds so I am not expecting to see a huge change going from 35 to 30 seconds.
