Let's say we don't add any of Sarr, Coward, Watkins, or Stojakovic. One crazy option would be to instead add 4-5 young players, all Sophomores, and develop them! We could have them for two seasons, which would also provide continuity from the 25-26 season to the 26-27 season.
For example, here are 5 potential Sophomores available still via the transfer portal:
George Kimble III, Eastern Kentucky, 6'2" 184-pound G
AJ Brown, Ohio, 6'4" 210-pound G
Kennard Davis Jr, Southern Illinois, 6'6" 215-pound G
Nick Dorn, Elon, 6'7" 200-pound CG
Josh Harris, North Florida, 6'8" 210-pound F
Add those 5 transfers to the following 9 players:
T Ivisic
Z Ivisic
D Mirkovic
J Jakstys
J Davis
T Rodgers
K Boswell
K Wagler
J Lee
That's a decent 14-player roster, with only one player (Boswell) out of eligibility after the 25-26 season.
