They've also beat teams ranked #1, #8, #13 and #14.
That's because they are a good team, but like a lot of good teams this year they've shown they can lose on any given night. Have now lost games in which they were favored by 11, 10.5, and 7 on the road. I really like their team. I just don't think they are clearly above the rest as Hicks' Guns mentioned.
