As the former POY, Caitlin likely will be the face, if there is a single face. Not only was she the POY, she was 2nd in scoring and 1st in assists. She put up huge numbers, led her team to an upset of the previously undefeated S.C. powerhouse and to the national championship game, and is probably the most exciting player in the nation. She hits bombs from the logo/Steph Curry range, plus she may break Kelsey Plum's career scoring record.
By New Years, Paige may also be getting comparable attention, especially if UConn is undefeated and she has regained her form. In my opinion, Paige has been the best player in the nation for the past 3+ seasons--or would have been if healthy.
I think Brink is the next best player. Bayou Barbie will get recognition too, though she is a one-trick pony. She is quick as heck, but she rebounds and scores from underneath only.
