There are a pair of massive top-10 showdowns this weekend in college basketball, two games that will have a sizable impact on next week's Power Rankings.
The first is Tennessee's trip to Auburn on Saturday. Tennessee has been up and down since winning its first 14 games, while Auburn is without Johni Broome and has looked vulnerable for the first time in a month in two of its past three games.
Iowa State's loss last weekend to West Virginia means any slipup from Auburn and Duke moves up to No. 1 -- although the Blue Devils have a difficult trip to Wake Forest (with its 10-0 home record) this weekend.
