But the skill and desire both players showed could lead to a scholarship offer in the coming weeks, and both players hold Rutgers in high regard.
"I sat down in coach (Greg) Schiano's office," the 5-foot-10, 180-pound Williams said. "They said they want to offer me, but they only have a certain amount of scholarships and they already offered them out. They said they had to call those kids and see if they're going to take them.
"I was so high on Rutgers, when I was up there, if they offered me, in my heart I would have wanted to commit, but I wouldn't be able to because of what my coach told me. I liked Rutgers that much."
Williams, who holds more than a half dozen offers, rebounded from what he turned a poor start to the camp to prove he was one of the best players there.
"I thought I did everything I could," Williams said. "I went up there, I really took it serious, I shut down some good receivers. I showed my athleticism there.
"I'm a competitor, so I want to compete at the level I know I can compete at. So I got a little pep talk, took a little walk around the inside of the stadium, and I pretty much came back and had a really good showing the rest of the day."
The 6-foot-3, 195-pound Gonzalez caught 39 passes for 599 yards and eight touchdowns as a junior, and he holds double digit offers.
And he is hoping the Scarlet Knights decide to make an offer.
"I'm actually in the same boat as Frankie," Gonzalez said. "I was very high on Rutgers coming in there. I was a little disappointed I left without an offer. I worked my butt off in camp. I like Rutgers a lot. Their weight room is the real deal, and their campus is really nice."
The close-knit bond within the team is also something that stuck with Gonzalez.
"One thing I thought that was really neat was the F.A.M.I.L.Y bracelets. Forget About Me, I Love You," Gonzalez said. "That's what coach Schiano preaches and he was telling me about it. He's big on the team being a family. When I was there I could see that. Everybody looks out for each other, and I just like that. It's really neat."
