They are absolutely for real. That's three ranked teams Nebraska has taken down in a row. Also, Vermont is ranked like 27th and they beat them by about 40 points.
There are only 3 teams in college basketball who are undefeated. UCONN, Nebraska, and Wisconsin-Green Bay. There is no reason why they shouldn't be considered a top 5 team legitimately after taking care of 4 straight quality opponents.......THREE of those four games were on the road.
