Ohio State is a fascinating case study. Along with UCLA, probably the two most improved teams over last year.
This year Mitchell and Alston are averaging 35 min per game. After that, McGuff has 4 players (Hart, Cooper, Doss, Craft) averaging 25 to 28 minutes, plus two more in the 12- to 15-minute range. OSU did lose one player early in the season: freshman Kaylan Pugh, a top-100 recruit from the Memphis area, who is now at Georgia Tech. I have no idea whether she left because of limited minutes.
Alston and Craft are the only seniors. Will there be enough room in the rotation for Mavunga, Harper, and Calhoun? In the frontcourt, I'd imagine that only 2 of the 3 "bigs" (Hart, Cooper and Mavunga) can start, but each can still average 25-30 minutes per game while keeping two of them on the floor.
That leaves 3 guard spots to be covered primarily by at least 4 players: Mitchell, Doss, Harper, and Calhoun. Doss is currently a starter and a reliable ball-handler (2-to-1 assist-to-turnover ratio), but probably not the scoring threat that Harper and Calhoun are (and none of them can touch Kelsey Mitchell, of course).
Of course, none of this takes into account the 3 elite recruits McGuff has coming in next year, plus Kianna Holland, who is out for the season with a knee injury.
It will be fascinating to see whether McGuff can manage this truly impressive ensemble of talent next year.
