He received plenty of tips from secondary coach Ed Pinkham, and as the camp progressed, his confidence rose.
It is quite an interesting time for Fuller, a class of 2012 recruit who has been Old Tappan's starting quarterback since his freshman season, but is being recruited as a defensive back by the Scarlet Knights.
"(Camp) went pretty good, I thought," the 6-foot, 180-pound Fuller said. "I could have done some things better in the first session we had, like learning technique and stuff like that I haven't learned with my team. I got the hang of it in the second session, and the second session I did pretty well in one-on-one.
"I think right now if I went to Rutgers, I would be on the defensive side."
"UConn has some good facilities and I like them," Fuller said, "but Rutgers has all-around great football program, academics are first in the nation, and they're facilities are really good, too."
Through his first two years at Old Tappan, Fuller's mark has been made on offense.
He was the starting quarterback as a freshman and sophomore, and last season completed 55 of 107 passes for 930 yards and eight touchdowns. He added 48 carries for 489 yards.
Schools are recruiting Fuller as a cornerback or athlete, which he doesn't mind. He does not have any verbal offers, but that could change.
"UConn was saying something about a soft offer, but I don't think they did because they didn't talk to me about it after they said it," Fuller said. "I want academics, first of all, and second is the football program."
