The Cardinal were the first school to offer him last September and are recruiting him for defensive end. "I was just at the Nike camp at Stanford last weekend (May 17 -18)," Renfrow said. "It was really beautiful there. The campus is great and they offer you one of the best educations around, plus they play in a very competitive Pac-10 conference."
Despite living nearly 3,000 miles away from Palo Alto, Renfrow says that the distance will not be a factor. "That doesn't make a difference," he said. "I have family near Oakland and I know my parents will travel wherever I go.
"I really like the coaches at Stanford too," he said. "I've gotten to know (assistant) coach D.J. Durkin and (offensive coordinator) David Shaw pretty well. We talked about their defense a lot and how I'd fit in. They told me about some drills I could do and things I'd need to know if I went there.
"I also got to speak with (head) coach Jim Harbaugh for a bit," he said. "He's a great guy."
The only other school in Renfro's top five that he's already visited is Connecticut. He says the Huskies are recruiting him for both defense and offense. "They have beautiful facilities," he said. "Everything there is really new and (recruiting coordinator) coach Matt Cersosimo is a great guy. He's been to my school a few times and they seem to really like me. I just gave them my highlight tape and they said they'll evaluate that next week. I think they'll probably offer me. I'm going to their camp this summer, so if they don't offer me after the tape they probably will at the camp."
Renfrow says he's also friends with Huskies freshman linebacker C.J. Marck. "We played Pop Warner football and we're pretty good friends still. We talk about football and recruiting too. He loves the coaches at Connecticut and he's really excited about the program and how they are still building."
In fact, one of the reasons Renfrow likes Connecticut so much is because they are still a "team on the rise."
"I'm definitely going to be watching Uconn next season," he said. "They really impressed me last season and I think they can keep it up. Nobody expected them to win the Big East."
Renfro says the other schools he plans to keep a close eye on are Virginia and West Virginia.
"West Virginia has been one of the top teams in the Big East the last few years," he said. "I have family in that area too and I've spent a lot of time there. I'm pretty familiar with them already and feel comfortable there."
The Mountaineers are recruiting Renfro as a defensive end, just like Virginia.
"Virginia is a great school," he said. "They have a really good education. They told me they really want me to come to their camp so that they can evaluate me in person."
Besides the Cavaliers camp, Renfro also plans to attend camps at Connecticut and Louisville.
"Louisville is recruiting me for tight end and I really like their offense," he said. "They are known for passing to the tight end a lot. I also like the Big East. They have a lot of really good teams and have become a very competitive conference."
Growing up, Renfrow says he used to follow Ohio State. "They would always win and I liked how balanced they always were," he said. "They are good on both sides of the ball."
But the Buckeyes are not recruiting Renfrow. "I've only gotten a few letters from them," he said. "They aren't really recruiting me."
In addition to his busy summer camp schedule, Renfrow also expects to take all of his official visits in the fall. "I'm gonna have to wait and take my trips," he said. "I probably won't decide on a school until after my senior season.
"I just want a nice campus atmosphere where I can get a good college experience," he said. "I also want to be prepared for the future after football and want to major in business."
Renfro finished his junior season (5-3) with 56 tackles and eight sacks on defense.
"I rush the passer well," he said. "I'm able to make all the plays when they come my way and I'm always going after the ball. I played defensive end last season but I like playing offense too. It doesn't matter which position I play in college."
He says the main thing he wants to improve on is "staying low and chasing plays down from behind."
Renfro benches 285-pounds, squats 400 and has a 29-inch vertical jump. "Me and our quarterback do a morning workout at 6:30 am," he said. "We do it Tuesday through Friday and in the afternoon I also run."
Renfro is also a good basketball player, averaging a double-double. "I'll probably only play football in college, but I'll consider both," he said.
He reports a 3.0 core GPA and a 1700 SAT. "I'm going to fill out my Stanford application after we're done with finals," he said. "They pretty much told me I'd need to score in the high 500's on each section, which is basically what I did. I should be able to get admitted."
