I'd be interested in Ned's take on this, but for all the time the article you linked spends on Jenner's dominance on draws, the numbers weren't all that amazing. I have seen girls, especially in high school, that can pretty much control a game from their dominance at draw controls, as they win >80% of the draws. Size helps, but it's not everything in draw controls.
Her older sister goes to Duke, so this isn't a huge surprise. Plus, if you look at it from the academic side, Duke really is a great university.
I'd also note that Jenner didn't make the roster of the Under Armour All-America Lacrosse Game. That's not the final word in talent evaluation, but usually the top players make the roster.
I could probably look it up, and Ned may know the info, but Jenner has probably been verballed to Duke for 3 or more years.
FWIW, the best girl's high school LAX player in SE PA this past year is headed to Syracuse. She's a great kid ... can pretty much score at will regardless of what defense the opponents throw at her (and they threw pretty much everything at her this year). I did mention to her in a joking manner that she should have gone to PSU. She laughed, and I didn't go any further with the conversation.
