Geno is going to have some tough decisions to make. Assuming Evina is not available this season, he basically has a rotation of 6 with whatever contributions he can get from Adebayo, Camara, Irwin and Bent.
Next year tho... Assume a core 3 of Williams, Walker and ONO. the other starters could realistically come from Westbrook, Makurat, Griffin, Bueckers, Muhl or Edwards. McLean is athletic but a bit raw. Gabriel is really raw. In big games, I could see a core rotation 7-9 depending on how good the newbies are and how fast they pick things up. Realistically, tho, in big games, I suspect it won't be 9. It's a great "problem" to have ("too much" depth).
This year is gonna be tough, no doubt about it. A LOT will need to come from the 2 freshmen. But next year I think they will all appreciate being asked to play less PT in games so the new studs can have a chance to grow and learn without being thrown into the deep end...
And the year after that, holy cow.
@MilfordHusky and I were chatting and he shared the story from back in the days when Shea was a senior and they had Hansmeyer, Sveta, Schuey, Big Rig, Cash, Bird, Jones, Williams and Kennitra Johnson. I forget who they were playing but in the 4th quarter, UCONN was continuing to blow out the other team, and a fan yelled out "Geno put in your subs". Another fan turned to him and said "All 5 of those players on the court ARE the subs"!!!
