The USA TODAY Sports high school football rankings landed with a split personality this week: the national Super 25 didn't move at all, but the regional boards tell a livelier story heading into Week 13.

Out West, rivalry weekend in Arizona did the heavy lifting. Chandler and Liberty emerged from the state's rivalry games holding the top two spots in the West Region Super 15, and the shakeup opened the door for a California team and a Utah team to crack the rankings. The Southwest board also got a fresh look as postseason play officially begins there, with teams re-sorted going into the playoffs.

The rest of the map was quieter. The Midwest Region's Super 15 is unchanged after a week in which the favorites simply took care of business, and the East Region saw a similarly sleepy slate with little movement in its latest rankings.

That calm extended to the national picture. With so many ranked teams idle in Week 13, the handful that did play rolled to comfortable wins — leaving the Super 25 exactly where it stood a week ago. With playoff brackets filling out across the country, that stability is unlikely to survive much longer.
