I think that, by and large, the coaching changes in the last few years have been improvements from what was left behind. So I think the conference will become more challenging over time with better coaches and recruiting, and I am glad to see that.
My favorite period was the mid- '80's when you had several institutions (Dean, Holland, Lefty), several up-and-comers (K, Cremins) and even a young superstar (Valvano). Better coaches makes for better competition, which makes for better teams by the end of the season.
