Since the 80's when Skip Bertman became coach, I'd say they have been. He is solely responsible for creating the program they have now. When he stepped down and became AD at LSU several years back, they had a few mediocre years. They seem to have righted the ship with the coach they have now.
They have a long way to go though to become a storied program like Texas or USC, but I'm happy with them. Just wish NCAA baseball got a little more national exposure during the season so I could watch 'em more.
