"It would be most comfortable to stay close to home, but it wouldn't be a problem going farther. USC is only 15 minutes away! They are a winning team because they won or almost won the last three or four national championships. I have chemistry with the team because the players are down-to-earth.
"And the academics at USC could give me a good degree for whatever happens after football," Warren said. "Even though USC looks great to me and they are recruiting me the hardest, I need to venture out of my backyard before jumping into a commitment.
"I plan to visit Ohio State in late July or early August. I like Ohio State a lot because they send cornerbacks to the NFL and they have winning tradition.
"The Cal Bears' head coach, (Jeff) Tedford, is a down-to-earth guy. He's personable. California is also closer to home, and I can see myself playing early there.
"I have a friend up at Oregon, Derrick Jones (wide receiver). He went to my high school. He's a little bit older than me, but we are good friends. Oregon also has an up-and-coming program," Warren said.
"UCLA has a lot of seniors graduating from my position, so I have the chance to come in and learn their defensive system. Plus, UCLA has a great academics.
"I plan to visit Michigan on the same trip as Ohio State later this summer. They send their defensive backs to the NFL. After watching them on TV, I know they have a big program—that Big Blue tradition," he said.
"Arizona State has a great offensive package. As a cornerback, I think I could contribute to turn up the defense to the same level as their offense. I could probably play early, too.
"I don't have a certain time I want to commit. I'll just make my decision when it comes to me."
Warren reports a 3.1 core GPA and an 880 SAT score which he retook in April.
