We recently released our High School on SI Power 25 national high school football rankings.

Now, we break it down by region.

No. 1 St. John Bosco’s 27-14 win over Santa Margarita led to a slight change to this week’s Southwest Region rankings, with the Eagles switching places with Basha at Nos. 7 and 8.

However, there’s the potential of a bigger shakeup next week, with the Bears facing fellow Arizona power Hamilton in a matchup of top 10 teams.

Meanwhile, Santa Margarita looks to rebound this week against Orange Lutheran, which was rocked Tuesday when it had to forfeit two games due to using an ineligible player.

Here’s a look at our Top 10 teams in the Southwest Region (Arizona, California, Hawaii, Nevada, New Mexico).
