I don't see West Coast teams play often, but other than Oregon I haven't been impressed by many West Coast teams I HAVE seen in the past few years. Too much dribbling, laissez faire defense, unimaginative offenses. Sorry if you're offended, but that's what I've seen. How many West Coast teams have contended in the NCAA Tournament in recent years?
There seem to be more excellent teams everywhere this year. I remember when UConn was in the Big East they often ran teams into the ground - after halftime opposing teams could barely move their legs. Overall conditioning is now greatly improved everywhere, coaching is much better due to more young, female coaches with positive, winning attitudes and players just seem more skilled.
