The 6-foot-7, 270-pound Cashman said the Scarlet Knights got in touch with Bulldawgs coach Frank DeLano last week, and he is expecting to hear much more from them in the near future.
"I haven't been in touch with them too much, but they called my coach and he gave them film on me," Cashman said. "I've been in touch with (Rutgers assistant) coach (Phil) Galiano, but not too much. They said they didn't know about me and asked where I had been and how I came out of nowhere."
Cashman added he isn't well-versed in Rutgers, but it is a program he is has paid attention to.
"Being so close, they're definitely a school where I have to root for them," Cashman said. "They've been having some good success the last couple of and it's exciting."
Cashman didn't attend Rutgers' junior day, but likely will make a trip up to campus during the spring. He also plans on attending Connecticut's junior day next weekend and is setting up a mid-March trip to Central Florida for junior day.
At this point, though, Boston College is the program he knows the most about.
"This process is just starting so I don't know many," Cashman said. "At Boston College, I got to talk to a couple of coached, and had a couple of conversations with the offensive line coach. I saw their facilities, and their stadium, and those were very nice."
Cashman also visited a number of Ivy League schools last summer, but may opt for an FBS program even if he gets an offer from Princeton and Harvard.
"I did a camp at Princeton last summer and went to Brown, Harvard and Dartmouth," he said. "I think right now, if it's possible to play big-time football, I think I want to lean that way."
Cashman played left tackle for Haddonfield, which won the south Jersey Group II championship in December. One of his goals for the offseason is the add 15 pounds.
