Wilson will win, but KLS is better than her, and she'll have more of an impact at the WNBA level. KLS is the best shooter in WCBB since Maya Moore, and at her size, she's nearly unguardable coming off a ball screen. Both players have great motors--KLS doesn't get credit for how she has improved her physicality. I do admit that A'ja affects the game defensively more than KLS. So I guess it's a toss up--but when you consider that A'ja's a senior and was the preseason favorite, it's hers to lose.
Personally I think Wilson wins - this is her year. She's a senior, won the NC last year, and puts up some of the best stats in the country for her position.
Having said that, I think Samuelson is the best all around player in the country. Her defense is vastly improved, she can drain the 3, is a good passer, has very good moves around the basket, and can post guards up in the paint. She's more a complete player than A'ja, but A'ja is not asked to play the way Samuelson does...
