Updated recruiting rankings

It's two weeks from national signing day, and ESPN Recruiting has updated its rankings for the home stretch.

The big Pac-12 mover is USC, which climbed up to No. 4. Four other Pac-12 teams rank in the top 25: No. 15 California, No. 16 Oregon, No. 18 Stanford and No. 22 Washington.

Here's what Tom Luginbill had to say about the Trojans' move:

It was inevitable, wasn't it? Lane Kiffin and USC made their move and now sit in the top five of the updated class rankings. The Trojans got a big boost from several players -- including No. 1 WR George Farmer and No. 3 QB Max Wittek -- receiving higher ranks in the final ESPNU 150 rankings, and they also were able to land a few more elite players. The scary thing is the Trojans are still in the mix for other top players and could climb even higher.

As for the updated ESPNU 150, it features 23 future Pac-12 players.

USC leads the way with seven on the list. California and Oregon both have five. Washington has three, Stanford two and UCLA one.

Arizona, Arizona State, Colorado, Oregon State, Utah and Washington State don't have any top-150 players as of yet.
