From the various academic and athletic programs the campus offers, Walker was expecting to get a great education to get him into college. What's he actually got in the last two years is more than he bargained for.
"It's impact on me has been huge," said Walker. "The school has taught me that nothing's ever given, that you got to work for it. It has helped me mature a lot."
Like most high school institutions, academics are priority number one, but Our Lady Good Counsel takes it to another level. According to the school, its graduating class of 2010 was awarded over $18 million in merit-based scholarships.
The Badgers know firsthand how important academics are to those graduates, as class of 2010 verbal commit Frank Tamakloe quit the team prior to spring football so he could focus on his studies.
"Academics always come first at my school," said Walker. "They can be hard but if you put the time in you'll be fine."
It's no surprise that their classroom work ethic has bled over into the weight room. With workouts practically every day, Walker compares the routine to a typical college program, especially since his school has its own strength coach.
That helped Walker transition onto the varsity level last year, registering 15 tackles and one interception in a reserved role last year.
"I feel like I'm a lot more physical and attack the ball really well," said Walker. "I am a big guy, so I can see a lot of what happens on the field. I workout pretty much every day and I give it my all."
Even in a reserve role, schools have started to jump on the 6-4, 195-pound safety. Walker picked up his third offer from Hawaii last week, which joins previous offers from North Carolina State and Wisconsin. Those offers join campus visits to Maryland, Penn State, Temple and Virginia Tech.
"I don't know much about the school (Wisconsin) other than them having a good football program," said Walker. "Relationships have been great so far. I have talked to coach Hammock and coach Ash a little bit."
If Wisconsin has its way, it'll also get a heavy look from Walker's teammate, Derrin Myers. A 6-2, 300-pound defensive tackle, Myers, who was unavailable for this story, got his first and only offer so far from Wisconsin. According to Walker, he views the Badgers opportunity in high regard, as well.
"He's one of my close friends," said Walker. "We'll go through the process, but (the Wisconsin offer has) been exciting for the both of us."
