Random perspectives from Cleveland

What kind of a sign is it when Purdue beats Duke in the shootout? Is it a good sign, or is it a typical sign? I remember a few years back when Purdue beat Arizona (who was number 1 at the time.) If I remember crrectly that was the year they went on to the Sweet 16 where they lost to Wisconsin. Does this victory mean that they will contend for the Big 10 title, or is it mearly another upset over an over-confident team that never really builds into anything else?
