Oh, he liked what he saw in Happy Valley. But when he did not receive an offer from PSU coach Bill O'Brien and his staff, it stung.
That was a little hard, Fuller said.
The Class of 2013 prospect added that at the time, Penn State did not like my size.
At 6-foot-1, he was carrying only 155 pounds. So between the Junior Day visit and PSU's Advanced Skills Camp Saturday, Fuller focused on adding weight. He chewed down some 4,000 calories per day and worked out with a trainer.
Fuller was one of the stars of Saturday's camp, making a series of outstanding catches and having several strong battles with Class of 2014 defensive back DeAndre Payne. And he was carrying 165 pounds on his long frame.
When camp was over, Fuller received a verbal offer from the Nittany Lions.
They like what I can do and think I'm someone they can teach, he said.
And with that, Penn State shot to the top of the four-star recruit's list.
Asked specifically where the Lions stood, he replied, Right now, first.
Later, he said his top five would also include Notre Dame, Ohio State (a childhood favorite), Clemson and Rutgers. The Scarlet Knights hold a special place with him, too, because that was my first offer.
Fuller said he now has a dozen offers. Asked when he might commit, he paused.
Maybe two weeks, he said. I'm just gonna see some other schools.
Another part of the delay is because he wants to absorb the big news of the PSU offer.
I never thought I'd be in the position to have any offers growing up, he said, noting that he did not begin playing organized football until eighth grade.
But Saturday night he and his family were making the short trip from University Park back to Philly. He was already planning on how to break the news of the offer to his friends.
I'm gonna post it on Facebook, he said with a smile. I'll be getting a lot of notifications.
