I think the best possible comparison for a potential role for Rice is Evina. Their games are very very similar in my opinion. Both have enough size and versatile skills to be quite comfortable at 1-3. Remember Evina was a point guard at Tennessee, but here with Paige and Nika she was not needed much there, and as a "swiss army knife" became more of a 2/3 and even played some at the 4.
I agree with some here that a PG is not "needed" in 22, but I don't think of Rice as a pure point guard, but rather a three position player who on this team would be more of a 2/3, and next year we lose two of those in Christyn and Evina, and Rice appears to be about as close to a clone of Evina as I can imagine.
So I think she could clearly find a role next year, the question is how big a role is required for her to be interested. I don't think she views herself just as a point guard, or we wouldn't still be in the mix. I suspect she also knows with two generational talents at PG (Paige) and SG (Azzi) that starting at either of those positions is extremely unlikely until they graduate. Her only realistic shot at starting in the first couple of years would be at the 3. There she still would have serious potential competition from Caroline and others, but in Evina she has an excellent exhibit A of how a big point guard can and has made that transaction successfully at Uconn.
