You raise a good point. Last year, playing a small team that worked together beautifully, the Huskies were 36-1, one basket short of the national championship.
Arguably the Core 4 + Danger will be even better this year, so why mess with something that works?
I could argue that while it may take longer for Z to mesh with the Core 4, once she does UConn will create tremendous matchup problems for opposing teams. Imagine a 6’6” Center who can pull opposing centers out to the 3-pt line, Gabby dominating opposing wings instead of playing the post, Lou posting up helpless 2 guards with Danger coming off the bench to speed everything up and blow the game open.
Whatever happens it sure is going to be fun to watch.
