I'm actually a bit skeptical. Has she earned a full-time assistant role at arguably the best program in the country? I mean yeah, she's one of the greatest players ever in the sport, but her coaching career is headlined by a volunteer role at Texas and some NAIA school. She's also still playing with the national team. She's worked with a ton of top-notch coaches, though, and I'm sure Cook feels good about this move and will work with her. This is the rich getting richer by getting one of the greatest ever to coach and recruit (not like we have a problem recruiting hahaha).
Also, how often does it happen where a coach of premier D-1 athletes is literally better at the sport than the players lol... she's on the downhill due to Father Time though, so probably only another year she could say that.
