Massey has Vanderbilt at 14, UCONN at 29 for SOS. UCONN's faced 1 team that will likely be a #2 seed (Iowa) where as Vandy has played 4 (LSU twice, Texas once, and South Carolina once). I wouldn't say that's a wash. UCONN scheduled well considering their conference but Blakes has faced tougher opponents than Strong has. People can make arguments based on efficiency, advanced stats, per minute stats, per game stats, impact on team success, etc. but both are excellent candidates and either would be very deserving if they win.
And last year Watkins won vast majority, she won 6 POY awards to Bueckers 2. Watkins (and Blakes) are both far more than just scorers. Juju was one of the top defenders in the country and a finalist for NDPOY, Blakes is an excellent creator for others and a strong defender herself. I'm not arguing that Blakes a better all around player than Sarah Strong but to insinuate she's just a scorer is inaccurate.
