Last summer, I posted this thread, in which I talk about UConn's all-time starting five, as well as UConn's Mt. Rushmore:

At this point, I think Stewie is on the all-time Husky starting five, along with sue, Diana, Maya, and Tina. Incidentally, this very same group of give was on Team USA for the 2014 FIBA world championships, and I would have given anything for them all to be in the same lineup, if only for a few minutes. At any rate, she's ahead of Rebecca Lobo for me, in spite of everything Lobo did for the UConn program.
However, Mt. Rushmore is challenging because influence on UConn history, as well as results, make for stringent criteria. Not only that, four is more exclusive than five, and there are only four spots on Mt. Rushmore.
Having said that, I'd argue that Stewie needs to win four NCs, ideally with four MOP awards, to be a lock for Mt. Rushmore.
As for GOAT, it'll still be a tough argument, but from a "body of work" perspective, I think the title would be hers. However, if my life depended on the outcome of a game and I got to pick a player first, my choice would still be Diana.
