Walker, a three-star outside linebacker, flew to Chicago to visit Northwestern for the first time. The experience allowed Walker to realize how it would feel living away from his home of Miami.
"It prepared me in case I decide to go to Northwestern," said Walker. "That way, my first time going out of state that far, it prepared me for how life would be."
During the visit, Walker spent time with Wildcat players and coaches, including a tour of Northwestern's campus and football facilities.
"It was great experience," Walker said. "I learned a lot about the Northwestern program. Got to talk with some of the players on the team and Coach Fitzgerald. It was a great opportunity for me."
For Walker, the most impactful portion of his visit was meeting with the people on campus--Northwestern players, coaches and the academic staff.
"There are a lot of good guys," said Walker. "It's a great group to be around."
A number of elements of Northwestern stand out for Walker. After the visit, he declared the Wildcats are his current leader.
"The most important thing is the academics," he said. "That's the number one thing. They're in the Big Ten, which is a great football conference. It was just a great chance for me to explore new opportunities after college, as far as internships and jobs."
As a junior, Walker finished the season with 65 tackles, five interceptions and four forced fumbles.
