While it was a terrific day for the Pac-12 overall, USC stole the signing day spotlight on Wednesday, hitting for the cycle in landing its top four targets.

The day began well for new coach Steve Sarkisian, as three-star cornerback Lamont Simmons (Jacksonville, Fla./Raines) faxed over his signature, but that was only an appetizer for the Trojans. With 19 scholarships available this year -- NCAA sanctions limited the Trojans to just 15 scholarships in this class and USC was able to roll four unused rides over from the 2013 class -- Simmons took the class to 16. Left on the board were a trio of Southern California ESPN 300 prospects in No. 9 overall prospect, cornerback Adoree' Jackson (Gardena, Calif./Serra), No. 24 overall prospect, athlete John "JuJu" Smith (Long Beach, Calif./Poly) and No. 67 overall prospect, offensive guard Damien Mama (Bellflower, Calif./St. John Bosco).

Sarkisian and the Trojans were able to land all three, giving USC one of the best signing days of any program in the country. The signings give USC 19 additions in the 2014 class, including nine ESPN 300 pledges, one ESPN JC 50 prospect and impact players on both sides of the ball. There is really no way to overstate how well Sarkisian and the Trojans closed on signing day, posting what amounted to a perfect day.

The Trojans wound up with the No. 1 class in the Pac-12, but the rankings in the conference were bunched at the top.

Stanford made a huge run late, landing commitments from all six recruits it targeted over the past two months. The Cardinal added signatures from ESPN 300 defensive end Solomon Thomas (Coppell, Tex./Coppell) -- at No. 25 overall, the highest rated Stanford addition since ESPN began its rankings in 2006 -- and three-star cornerback Terrence Alexander (River Ridge, La./John Curtis Christian). Though the Cardinal lost a late commitment from defensive end Uriah Leiataua (Compton, Calif./Dominguez), it was a very strong visit and a terrific class headed to the Farm.

Alexander wasn't the only recruit from John Curtis Christian to commit to the Pac-12, as Oregon and UCLA took their biggest commitments of the day from that program. The Ducks landed ESPN 300 safety Mattrell McGraw, while UCLA picked up its lone signing day commit in Kenny Young.

Oregon missed out on Smith and defensive tackle Trey Lealaimatafao (San Antonio/Earl Warren) but was able to land safety Khalil Oliver (Meridian, Id./Rocky Mountain) in a battle against Washington.

UCLA coaches will likely be disappointed with the day. Although the Bruins did reel in Young, UCLA missed on Thomas, No. 1 overall wide receiver Malachi Dupre (River Ridge, La./John Curtis Christian) and the Southern California trio, which made matters worse for Jim Mora & Co. by committing to the Trojans. UCLA brought a very good recruiting class into signing day and did a good job of holding onto everybody, but the Bruins took some big swings at some big prospects across the country and didn't get the results they were hoping for.

Arizona State slid a few spots in the national rankings, but the Sun Devils did everything they could on signing day. Todd Graham brought a relatively full class into the day and was able to add two huge signatures in ESPN JC 50 prospects defensive tackle Dalvon Stuckey (De Funiak Springs, Fla./Pearl River CC) and cornerback Kweishi Brown (El Cajon, Calif./Grossmont). The Sun Devils were also able to hold onto another junior college standout in wide receiver Eric Lauderdale (Fayetteville, Ga./Saddleback College), who received a significant late push from Florida.

Arizona was relatively quiet. The Wildcats brought in a huge list of verbal commitments and didn't lose anybody off the top of the class, landing five ESPN 300 prospects. Defensive tackle Marcus Griffin (Bellevue, Wash./Bellevue) was the big addition, as the big lineman selected Arizona over Cal, Mississippi State and Washington State.

Oregon State grabbed a signature from offensive guard Kammy Delp (Pomona, Calif./Diamond Ranch), who will play defensive tackle for the Beavers. Utah announced defensive tackle Lowell Lotulelei (South Jordan, Utah/Bingham) as a part of this class after he attempted to sign with the Utes in 2013.

Washington's big addition came Tuesday night in the form of ESPN 300 safety Bishard "Budda" Baker (Bellevue, Wash./Bellevue), but Chris Petersen and the Huskies also received a signing day commitment from intriguing 6-foot-5 receiver Brayden Lenius (West Hills, Calif./Chaminade). The Washington State Cougars closed with their second four-star commitment in this class, safety Deion Singleton (Paco, Wash./Chiawana).

But the day in the West belonged to USC, which jumped from No. 4 in the conference to landing the Pac-12's top 2014 recruiting class. Nationally, the Trojans moved from No. 24 to No. 15 overall.

Stanford (15th), Arizona State (21st) and Arizona (23rd) all finished among the top 25 recruiting classes in the nation.
