As both hail from the Washington, D.C., area, they will be able to get along well, as both visited USC officially over the past weekend. The most important transfer additions of the off-season were the decision by Addison to go to USC and the decision by Williams to join the team.

In his statement posted to social media, he said he would always be grateful to the University of Pittsburgh.

Winning an Atlantic Coast Conference championship is ours forever. The true friends will last. He wrote that a part of him will always be H2P.

I have carefully considered the advice of my family and close friends and weighed both the risks and benefits of my decision. I respect that other people may make a different choice. I will enroll at USC to continue my development as a student athlete.

The most outstanding receiver in the country last season was Addison, who won the Biletnikoff Award. He visited USC and Texas after entering the NCAA transfer portal. He considered staying at Pitt, but decided against visiting either Alabama or Oregon.

Pittsburgh lost its best returning player after going 11-3 last season, and that is a blow to the team. USC rebuilt its roster so much in the first year of coach Mike Riley that a majority of the players are expected to come from the NCAA transfer portal.

According to sources, Pitt coach Pat Narduzzi had a number of angry phone calls with Riley soon after Riley broached the topic of entering the portal. There is no known evidence of tampering.

The transfer of Addison has been viewed as a beacon of change. The idea of an established underclassman roster jumping programs was not something that happened in college football until recently. A flurry of rule changes has made fluid player movement part of the sport.

Williams transfer was viewed as a collision of one-time transfer and name, image and likeness rules, but it was viewed differently because his college coach at Oklahoma, Riley, left for USC and he followed him. All rosters are fluid and the sport's biggest stars can jump from program to program with relative ease.

Sources made it clear that his professional future was going to lead his decision-making.

USC has one of the best wide receiver duos in the country with the addition of Mario Williams. Last season, he caught 100 passes for 1,593 yards and 17 touchdown. He is projected to be a first-round pick in the NFL draft, but he is only 6 feet and 175 pounds.

Mario Williams, one of the country's top transfers, earned True Freshman All-American honors last year. Williams caught 35 balls and scored four times. The son of Jerry Rice averaged 14.2 yards per catch in Colorado last season.

As the lure of the prolific offenses he built and called at Oklahoma have moved their way over to Los Angeles, the optimism behind Riley's hire at USC has further strengthened. The USC offensive line has questions and the defense was one of the worst in the conference last season, but there are key pieces that have transferred in to help the offense.
