Nevada has been a great team at home and on neutal courts. I thought they were pretty impressive against UCONN early in the year, and if they were @ Nevada that day, they would have won.
Nevada is a tough place to play, and this is just a therory but, I think the altitude makes it tough for teams from sea level (as far as shooting %).
THen again, like Capt said, I might be overthinking this, but no way I play Kansas and give up 6 or 7 points.
