For what little it may be worth, KenPom provides line-up and positional data for the last 5 games of each team's season. While it's admittedly imperfect, here are the numbers on our transfers:
In '21, Dallas Walton played 29% of CU's minutes at center, and never lined up anywhere else, understandable for a 7-footer. (I believe the positional data is based, at least in part, on height, so you aren't going to see many folks able to bump him). In '20, he played 7% of their minutes at center and in '18, he was at 51%. He is never recorded at any other position.
Sy doesn't chart in the last 5 games for Ole Miss. In '20, he played 56% of their minutes at center, and was exclusive at that position. In '17, he was 20% of VT's minutes at center, and again didn't chart anywhere else. I'm not sure where the idea of him getting minutes at the 4 comes from, as he appears to have played C exclusively, and I don't see the triumvirate of him, Walton, and Tariq being so dominant that 40 minutes simply isn't enough to go around.
LaRavia played 82% of ISU's minutes at center, and nowhere else in '21. As a freshman in '20, he played 36% of their minutes at PF and 25% at C. I think it's more reasonable we see a few minutes of him at center than that we see Sy or Walton at PF.
Monsanto played 34% of ETSU's minutes at SF, and 41% of their PF minutes.
Alondes Williams played 31% of OU's SF minutes, and 18% of their PF minutes in '21. The prior year, he played 21% of their SG minutes.
Just out of curiosity, I looked up last year's transfers as well. Williamson went from an exclusive PG at ETSU (67% and 80% in his two seasons there) to a primary SG with us (29% PG, 55% SG). Antonio was mostly a SF at UNLV (36%, vs. 7% SG and 5% PF) but slid down more often for us (29% SF, 14% SG). DuBose was a PG/SG hybrid at HBU (56% PG, 27% SF) who was a pure SF here (53%). Jalen Johnson pretty much stayed at SG/SF (9% SG, 24% SF at UT, 6% SG, 8% SF here).
For the sake of context, our team returns 91% of its PG minutes (62% Whitt, 29% Williamson), 55% of its SG minutes (55% Williamson), 0% of its SF minutes, 65% of its PF minutes (65% Mucius), and 0% of its C minutes. Obviously, the biggest need is on the wing, but I feel like we'll be sliding Mucius out to SF a lot more often.
