Walker, a running back and defensive back, and DuBois, a defensive back and quarterback, both unofficially visited Rutgers on Friday and each picked up their first offers.
"I wasn't expecting to get it," Walker said. "They said I'm a great athlete, that they're looking forward to seeing me more, that I'm going to be a good player in the future."
The 5-foot-11, 191-pound Walker already has five varsity games of experience, and he is expected to get significant playing time in 2013. He rushed 28 times for 275 yards and four touchdowns as a freshman playing varsity, and the Scarlet Knights already have a strong relationship with DePaul Catholic and are looking to further it.
"I really like the program," Walker said. "A DePaul Catholic graduate (Davon Jacobs) is there, Justin Nelson just committed, Kiy Hester committed. We have little talks in the locker room about going there so I'm looking forward to going there.
"I like being there. I feel like when I'm there, I'm home. I like the coaching staff. They're really great."
Walker can play on both sides of the ball, and he has plenty of time to make that decision.
"To be honest, I like running back and I like corner," he said. "I'm an athlete and I'm willing to make my team better, so whatever my coach wants me to play, that's what I'm willing to play."
Miami, Michigan State, West Virginia and Florida State are also each looking at Walker and DuBoise, who is a 6-foot-1, 186-pound defensive back. He doesn't have as much varsity experience as Walker, but the Scarlet Knights project him as a Big Ten-caliber player, which is evident by the offer.
"For me to only be going into my sophomore year, it means a lot to get the offer," DuBois said. "They said they want to keep a lot of Jersey talent home, and they said I was a very good player. I know it's a very good school for academics, and the football program is building up."
DuBois spent a lot of time in the offseason working to improve several aspects of his game.
"I worked on my footwork, my football IQ, and my speed," he said. "I was going over stuff with the coaches and I worked on how to react on certain routes."
