"When my Mom, Dad and I walked into the Indoor Practice Facility, and we were all greeted like we were already part of the family, I knew I was home," said Walker, a 6-2, 195-pounder. "Ole Miss has a lot going their way right now and they're doing it with a lot of young players.
"If I go in there and put in the work, which I plan on doing, I'll get my chance to play early and be in a program that's on the upswing."
Walker attended camp at Ole Miss last summer and had an inkling he would accept a scholarship offer. The Rebels were the first.
"I felt comfortable at Ole Miss back in the summer. Other schools, like Mississippi State and LSU and Alabama, have been recruiting me, but Ole Miss was the first to offer," said Walker, who has been timed in the 40 at 4.48.
Callaway Coach Daryl Jones believes the Rebels are going to get a good one.
"Ronald is a great kid. He's very popular and he's serious about football," said Jones. "When he was a freshman, he started for the basketball team, but he decided to give that up to dedicate himself to football. We don't see that much around here. This is a basketball crazy town, but Ronald decided he wants to be a football player.
"Ronald is very athletic and his demeanor on the field reminds me of a current Ole Miss player, Denzel Nkemdiche. He plays 100 miles an hour and has a lot of energy. He's all over the place."
Jones used Walker quite a bit at outside linebacker to blitz off the edge.
"I can see him as a safety or an outside linebacker in college. It depends on what his body does. He could be a 2056-210 safety or a 225 outside linebacker," said Jones. "I really like him at outside linebacker though. He's so athletic, he'd be a terror there, in my opinion."
Walker says he is "done" with recruiting.
"I talked it over with my parents and we made the decision as a family. We're finished. It's final," he said. "Now I just have to go to work this next year to get better at everything.
"I want to work my speed, strength - everything. I expect to be over 200 my senior season and to keep going from there."
The Rebels have also offered two more Callaway players - OL Rod Taylor, a 6-4, 305-pounder who will be a "national" recruit and LB Breeland Speaks, a 6-3, 255-pounder.
"We have three SEC players on our team, so we should be pretty good next year," said Jones, whose team was 5-6 last fall.
Meanwhile, Walker is set to be in the Rebel fold for 2014.
"I can't wait. I'm going to keep working hard on football year-round and when I get to Ole Miss, I'll be ready to compete," he closed. "I'm very excited."
