In the final updated ESPN recruiting class rankings before national signing day, six Pac-12 schools remain among the top 40 classes in the country, and all are within striking distance of claiming the top spot in the conference. Arizona State remains No. 1 in the conference and No. 17 in the nation, and Stanford made a big jump for the second straight week, moving to No. 2 in the Pac-12 and No. 19 overall. Arizona slid one spot with Stanford's move, checking in at No. 21, and USC and Oregon remain tightly bunched at Nos. 24 and 25, respectively. UCLA rounds out the group from the Pac-12 at No. 28.
