So what changed this offseason? In short part, nothing. Villanova got better at defense, and their luck regressed to the mean this offseason. That's really about it. If this team could play better offense, (they're improving,) they would probably be even better at defense.
The true measure of a coach's performance is how much a team improves over the course of a season, and there is no question as to the improvement of the 2012-2013 Villanova Wildcats. I think we know what man deserves the lion's share of the credit for turning Villanova from a 13 win team last season, to one that is only a few wins away from making the NCAA Tournament.
