Ayanna's best game before today may have been against Maryland. I think it's situational for her. In high school, she was usually the tallest, strongest kid on the court by a wide margin. At UConn, she's by no means the tallest kid in any game, but she is as strong as anyone she meets.
In games against teams without a lot of really tall kids, I think it's easier for her to see how to use her strength, and the Maryland game was a case of this. They aren't a really tall team, so she wasn't paralyzed by fear of getting blocked (which leads to excessive shot-fakes) and can just go right up with the ball on putbacks.
DePaul is another team like this, and it has the ironic advantage that Ayanna gets matched up against another strong kid, Morrow. I think this is the sort of challenge she thrives on, muscling up against strong opposition. She got a monster block against Morrow (and another against someone else) and tore a few decisive rebounds away from DePaul, and the putback was awesome. This was a glimpse of the player she will become, and is an experience I think she can build on.
