Personally, I didn't see Wisconsin as a "boring" team last year and their combination of skill, team play, and even athleticism last season was truly elite. Kaminsky drew raves from Charles Barkley during last year's tournament. Observers were calling Sam Dekker one of the best wings in the country at elite camps this summer and he's rated as high as a lottery pick on some mock drafts. As far as Ryan hitting a plateau, well that could be true, but I wouldn't be surprised at all if his team this year managed to go one game further.
Hate Wisconsin and Ryan as much as you want (although, personally, I don't get the satisfaction some people get from feeling that kind of stuff; seems rather childish, pedestrian, and a waste of emotional energy to me), but a very good team and coach are what they are.
