The 6-foot-4, 225-pound middle linebacker, who will enroll at Rutgers on June 28, was a regular at spring practice, and learned the level of intensity and preparation needed to practice at Rutgers.
"It was huge for me to (pick a school) close to home,'' Milewski said. "I think I got a pretty good grasp of the defense going in, that now in the summer time, I'll continue to learn what I've been learning, and getting more in-depth into the defense. But I think I'm lucky because I'm ahead of the game knowing the defense.''
Another thing that taught Milewski about what awaits at the college level came when he played in the New Jersey vs. the Northeast all-star classic at Rutgers Stadium earlier this month.
"That was like the first taste of college football because the speed is so much faster that college football is played at,'' Milewski said. "I know these kids are still in high school, so the college game is even faster.
"Honestly, the biggest thing is not the speed of the tailbacks, it's the speed of the linemen. People who weigh all those pounds shouldn't be able to move the way they move. It's pretty crazy."
In high school, Milewski was a fast riser. He was lightly recruited until the midway point of his senior season, and appeared headed to Monmouth before Rutgers and Connecticut became involved.
Milewski quickly committed to Rutgers, then finished a strong senior season by making 96 tackles, intercepting three passes and registering a pair of sacks.
But Milewski doesn't think that success means early success in college.
"Everything on the college level is so crisp,'' he said. "In high school, it was knowing about what you're supposed to do before the play and knowing where you'll line up, and then just having your body react the right way.
"In the college game, it's getting tough mentally. The offenses have so many more formations, way more than high school. Hopefully, I'll be able to make that adjustment and do well.''
With sophomore Steve Beauharnais starting and Jim Dumont as the backup, it should give Milewski time to learn the system, and understands what Rutgers wants from its middle linebacker.
"Steve's a great player, and he's so fast to the ball,'' Milewski said. "I just have to learn as much as I can from him, and all of the linebackers there. I can't go in there thinking I'm going to know more than anybody. I'm going in as a sponge and trying to build as much knowledge as I can from the coaches and the players in front of me."
Milewski graduates from Sayreville on June 23, and does have a plan before heading to Rutgers. "I think I might sleep,'' he said jokingly. "For three days straight I think I'm going to take a nap.''
