"I didn't really see any [cons]," said McCollum, who is primarily being recruited as a defensive end. "I could definitely see myself at Northwestern."
During his day on the NU campus, McCollum said he took in the early morning D-line meeting, a full Wildcat practice, a tour of the school's lakeside campus and even a meeting with an academic services adviser.
Though the 6-foot-3, 235-pound recruit said he enjoyed his whole trip, he indicated the team practice was the highlight of the day.
"I really liked the tempo of practice," McCollum said. "I liked how they had a lot of competition between offense and defense in drills, but also teaching one-on-one … You can tell they really care about the players."
However, McCollum noted, several other schools remain firmly in the race for his services. The junior standout said he is considering trips to West Virginia and Marshall in the near future, as well as an invitation to attend Eastern Michigan's spring game.
McCollum – who has also taken snaps at fullback, tight end and linebacker - said most schools have intimated that he fits best at defensive end, but he added that he has not "gotten too far into the specifics" just yet.
What does seem certain, though, is that Tuesday's trip to Evanston will not be McCollum's last, as he plans on attending a Northwestern camp in early June.
In the meantime, McCollum said he will be working to improve both his strength and speed – and likely avoiding any early commitment decisions.
"I'm going to take as much time as I need to," McCollum said of his decision timeline. "It'll probably be up until February – I don't see any rush."
