The 6-foot-6, 260-pound prospect has been undertaking a training regiment that has limited his time for unofficial visits this offseason and it could stay that way for awhile.
The last trip Roberts took was to Stanford a couple of weeks ago. While there, Roberts enjoyed taking in the sights and meeting with the players and coaches.
"Stanford was pretty amazing," Roberts said. "It was pretty cool. I got to see the whole campus and spent the night and learned about their program."
Roberts said that another Pac-12 school, Arizona State, could receive a visit next week.
"My grandparents have a house down there so I'll probably visit Arizona State just because it's right in the area and I can check it off the list," he said.
After that, Roberts said he isn't planning on doing anything until summer arrives. Before that though, he could publicly announce his top schools.
"Before spring ball starts I'm going to try and narrow all of it down to five schools," Roberts said.
Of the schools that have offered Roberts listed Stanford, Washington, USC and Oregon as the ones recruiting him the hardest right now. However, a few other schools are showing interest from across the country.
With Oregon, Roberts said that he and offensive line coach Steve Greatwood have been developing their bond on a weekly basis.
"We have a pretty good relationship, really open," Roberts said. "He just asks me how everything is going and how my family is."
One of the big topics they've discussed is Roberts visiting Eugene sometime this offseason. Although nothing is officially scheduled, Roberts thinks the trip will happen.
"I think I'll probably go down and check them out," he said.
