"The kids up here are big compared to Florida," the Class of 2014 Wide Receiver said. "They're big cornhuskers. Back in Florida, you find a couple of them and then a bunch of little, fast kids."
Roberts is transferring from one outstanding high school program in Tampa Plant to another in Carmel High in the Indianapolis area.
"I'm having to get used to a different type of climate," he said. "The air up here is definitely drier. When I first got here, my throat was very dry."
On a positive note, Roberts receiving exposure in two parts of the country has helped earn him more attention. He reported scholarship offers from Iowa, Indiana, and Purdue of the Big Ten, the SEC's Florida and Miami of the ACC.
"It's been going much better than I expected," the 6-foot-2, 196-pounder said of his recruitment. "In the spring, I got my first five offers and I wasn't expecting anything to happen until my junior year. At the beginning, it felt really fast, but it's kind if slowed down a little bit for the moment. I'm enjoying it so far."
Roberts says he runs the 40-yard dash in 4.51 seconds. He describes himself as a physical receiver.
"I think it might be the toughness I have to make the tough catches or making the key block to free the running back running down the sideline," Roberts said of why he feels five BCS schools have extended offers to him. "I really have been trying to improve my run after the catch. I'm hoping that can be another variable I can add to my game."
Roberts said that he claims no favorite among the schools recruiting him. He's taking his time with the process.
"I was thinking some time during my senior year," Roberts said of when he might commit. "In a perfect world, I would like to do the three-hat thing at the end of my senior year. But the way recruiting has changed now, I may have to make my decision earlier."
Iowa moved early on Roberts. The Hawkeyes are doing what they can to earn a commitment from the wideout.
"I'm building a good relationship with Coach Eric Johnson right now," Roberts said. "It's really hard because he can't Facebook me or anything. I call him once every couple of weeks to check in. He's a pretty cool guy.
"I really like what he's telling me about he campus and everything. I definitely have to go out there and take a visit at one point."
Roberts. who attended the Florida spring game and visited Miami on Tuesday, will camp at Stanford next week.
"I'm probably going to check out Indiana, Purdue and Iowa's campuses this summer," he said.
