Very, very few changes this week in the RUGBYMag.com College Premier Rankings.

Navy and Army move up ahead of St. Mary's which slips down thanks to their close game with Central Washington. CWU moves up a hair.

Air Force is once again the big mover, as they lose, but by only seven points to Utah, who slide down a bit.

Cal Poly edhes up.
