Roback does not hold a verbal offer from Rutgers, but hopes that his throwing session in front of Spence put himself high on the Rutgers recruiting board.
"I'm supposed to talk to coach Spence soon," Roback said. "He came to see me work out last week and we're going to talk to him about where things stand. I'm just waiting for him to get back after being on the road and we'll talk."
The 6-foot-4 Roback holds verbal offers from Bowling Green, Miami University, Ohio and Toledo. During the spring evaluation period, Indiana, Boston College, Wisconsin and Kentucky also came to see him throw.
With multiple top regional quarterbacks committing in the last two weeks, St. John's head coach Doug Pearson expects for Roback to start getting more offers.
"The dominoes are falling and I think that's going to be good for Brogan," Pearson said. "You see a guy like Kevin Olsen from New Jersey commit and now all the schools recruiting him are going to look for someone else."
Roback visited Rutgers earlier this month while in the area for an Elite 11 combine in New York.
"When I visited Rutgers, it was more than I expected," Roback said. "Their facilities were top notch. The campus and everything, how it's laid out, is really different. It's different from anything I've seen, which is good, but overall I really liked it a lot. I talked to coach Spence and [head coach Kyle Flood] for quite a bit, so overall it was a good visit. My parents liked it, too."
Roback hopes his in-person visit helps put himself in better standing for an offer from the Scarlet Knights, he said.
"I think they know what they need to see if they're going to offer me or not," Roback said. "He's been to see me throw. I've met all of the coaches when I visited the campus. I don't have to come to camp or anything, so hopefully they decide to offer me."
Roback has no leaders at this time or specific timetable for a decision.
"I don't really have a deadline or anything like that," he said. "The only thing I'm really thinking now is to try and get it done before senior year. I want to focus on football. And just have fun with my teammates and win a state championship."
