A couple of things. I don't really expect Westbrook to stay at UCONN 3 years. She'll have her degree by May 2021 (I assume), so I imagine she'll go into the draft then. So the roster would be 9. Fudd would make 3, so a roster of 12. Could Geno go for 13? I think he would if he got the right player.
Usually back to back big classes don't happen. Ideally it would be 3,4,3,4,3,4, etc. One time though UCONN had back to back 5 player classes. 1997 (Abrosimova, Schumaker, Glenney, Clark and Czel - not sure if Czel was a w/o though) and 1998 (TASSK). So IF Geno could pull a class of DeBerry, Poffenbarger, Fudd, and 1 or 2 of Ducharme? Iraifen? Miles? Von Oalhofen?. Damn straight, I think he'd take it.
Having essentially 3 classes of 2 right now (Walker/Westbrook, Williams/ONO and Griffin/Makurat) leaves a lot of room for the next couple of classes. 5/4/3 would be kinda nice.
