Olsen, who holds double digit verbal offers, already has a strong relationship with the Rutgers staff, and this trip gave him a chance to watch how the coaches operate in practice.
"I like (offensive coordinator Frank) Cignetti and I like the whole coaching staff there," the 6-foot-3, 189-pound Olsen said. "I feel when you go to a high-tempo practice like that, it's a lot different than what we do at my high school, so it's just great watching all those great players."
Olsen, who made an unofficial visit to Rutgers in May and met with coach Greg Schiano, already holds offer from Rutgers, Miami, Florida State, Iowa, East Carolina, North Carolina, Wisconsin, Michigan, Michigan State and UCF.
But unlike many of the other schools, Olsen already has a strong relationship with Schiano because of the recruitment of his brother, Greg, who ended up attending Notre Dame and is now in the NFL.
"It's a pretty good one," Olsen said of his relationship with Schiano. "I've known him for a couple of years, since I was a little kid, and he was recruiting my brother. So we have a pretty good relationship right now."
Although he has been on Rutgers' campus several times, he is still learning about the school. "I went on a quick visit and that was kind of it," he said. "Down the road more, and as we get to my choices, I'll learn more about it."
Olsen said he also isn't going to pick a school based on location.
"I'm going to go where they want me," he said. "It doesn't matter if it's here or wherever."
Olsen is coming off a sophomore season in which he completed 95 of 171 passes for 1,341 yards, 15 touchdowns and six interceptions while leading the Patriots to an 11-1 mark and the North Jersey Group III state title.
However, Wayne Hills will have to replace running back Brian Dowling, who ran for more than 1,800 yards and had 432 receiving yards last season.
"I think we're going to be pretty good," Olsen said. "We have a good offensive and defensive line. We return a lot of starters there. Every kid we return there has played in a big game, or started at that position but one. Replacing our running back will be tough. You never replace a guy like that, so we're going to have to have a couple of guys chip in and do what he did."
