Got to know each other well during Skylar's recruitment by Stanford. I think I recall Wiggins rooting for the Irish during the 2011 and 2012 Final Fours. That should be cool for Skylar to play with her.
Tulsa will have better attendance than Chicago. Add the fact they drafted one of her best friends and I bet Diggins is psyched about it. It's a young team and she's familiar with a good number of their players too.
