Teams that move away from their roots

I just read a very good article that discussed the troubles Wisconsin has had over the last couple of games because they have moved away from their characteristic defensive-minded team. The single biggest thing Steve Shields' teams have been known for over his tenure is perimeter defense. They defended the 3 with bulldog tenacity. This year we do NOT do that, and it has killed is a few times this year. I do not know what has changed, but we need to get it fixed. We are getting away from our roots, and that is never good. You can add good things, but you cannot desert what brung you.
