Liston. She is better than Liston. I really don't see her as an AA candidate.
OK, so let's start by looking at their stats:
L: 17.3 PPG, 57% 2PT, 48% 3PT, 85% FT, 5.2 RPG, 1.61 APG, 2.27 TOPG, 0.2 BPG, 0.55 SPG,
H: 13.9 PPG, 58% 2PT, NA 3PT, 67% FT, 9.1 RPG, 0.91 APG, 2.69 TOPG, 1.1 BPG. 0.97 SPG
So, what do those numbers tell us?
First Harrison is the better defender. Although this is mostly an eye test, it can be gleaned from some parts of the box score (a post having more steals than a wing player, for exaample). Second, Liston is a much, much more efficient scorer. Her true shooting percentage is 68%, whereas Harrison is at 62%. But in scoring efficiency is larger than that, because of two factors. First, many of Liston's shots come from self-creation or very higher percentage perimeter passing. Many of Harrison's shots come from relatively risky entry passes (and post players usually don't get credit for turnovers resulting in passes to them). This is why post players are expected to shoot a higher percentage than guards, and the fact that Liston is shooting almost as well from 2 as Harrison is is pretty startling. Second, Liston is carrying a higher scoring load than Harrison which will (necessarily) lower her scoring efficiency. To think of it another way, if Harrison had to increase her scoring to 17.3 PPG, she would have to take (possibly much) lower percentage shots to make up the difference. Any time a player is scoring at a higher rate AND more efficiently than another, it makes a big statement.
Just as importantly to me is how Liston has done it. After Gray went out, he numbers skyrocketed as she had to take more responsibility for the team. When Jones went out as well, she switched over to point-guard on a now very undermanned team and got her team past North Carolina twice. She has impressed tremendously with her senior leadership in the last few months and, while she is one of the last one's to get in, has performed consistently better than Harrison throughout the year.
