As of now, I would say that Maddy Siegrist is the clear front-runner for BE POY. With all due respect to Aaliyah Edwards and her outstanding level of play, Siegrist is single-handily carrying Villanova. She leads the country in scoring, almost averages a double-double, shoots over 50% from the field, 40% from 3-pt land, 85% from the foul line, while taking 20 shots a game. She outplayed Morrow recently in a game where Morrow launched 34 shots.
Morrow is an incredible talent, and Edwards is having a phenomenal season, but UConn possesses more weapons, despite its injury list and continued bad luck. Villanova would be in the bottom half of the BE if not for Siegrist on their team.
Maybe when UConn plays Villanova, the DPOY and/or POY might become finalized, depending on the job Aubrey does in covering Siegrist.
