What you say about Ann Strother could just as easily be said about Breanna Stewart as a freshman. Stewie at that time would have been happy to hang out at the 3-point line, as Geno noted at the time. When she had a shooting slump in mid-season, Geno finally convinced her that she needed to have a more versatile game and play both inside and outside, developing both sets of skills. We have seen the results.
Since Geno has already made the comparison between Stewie and KLS, and has urged KLS to "play like Stewie", I would expect him to push her towards a similar trajectory for her future UConn career. That will be particularly important to allow her to make a contribution while her 3-point shot continues to desert her.
And I do think that over time, KLS can be successful in the paint -- maybe not as successful as Stewie, but successful enough to be a serious problem for opponents at both ends of the floor. The question is whether she will embrace or resist that role. But if she came to UConn to see how good a basketball player she could possibly become, and if she sees the example of Stewie (who has probably told her the saga of her own freshman year), she should be motivated to do that.
