i don't think it's that sudden. this is their first top 10 class under white but the program has been consistently getting top 20 classes for the last decade (median class of 18/19!) theyre just a top 15-20 bball program in general. it's not like white has gotten off to a bad start by winning a game in the tourney 3 years in a row and never having fewer than 20 wins in a season. sounds pretty good to me.
