A lack of major upsets this week in college football translated into a lack of movement in the AP and Coaches polls.
Clemson narrowly avoided an upset at home against Syracuse and dropped down two spots to No. 4. Mississippi State and Duke were the only dropouts on Saturday after losses to conference foes Florida and Virginia Tech, respectively.
Colorado and N.C. State were the biggest movers, as each entered the rankings for the first time this season after victories over UCLA and Virginia, respectively.
