"I remember when I was younger I thought I had no chance," said Walker, now one of the most coveted prospects in the 2013 recruiting class. "I had no chance of anything like this."
It was likely hard to imagine he'd enjoy this trajectory on the court this soon, as the five star power forward out Bonifay (Fla.) Holmes County is ranked as the No. 6 prospect in his class by Scout.com.
And he has the offer list to show for it.
"Last offer I got was a week and a half ago from Kansas State. I now have 21 offers," said the 6-10, 205-pound Walker. " Things are going really good so far. My recruitment is really now starting to pick up and I have just been getting offers… It's been a blessing."
And where there's top talent you'll usually find Ohio State's coaching staff, as both head coach Thad Matta and assistant Dave Dickerson have been hot on the trail of the young star.
Already offering Walker a scholarship, both Matta and Dickerson have been in close contact with the junior. Walker, who some would say will be a tough pull for northern schools out of Florida, said he was high on the Buckeyes.
Walker, however, said distance isn't a factor in what school he ends up choosing.
"Everything (in my recruitment) is open right now, but if I had to do a top five I'd say Ohio State, Florida, Kentucky, Florida State, and Kansas," Walker said before continuing on about what he likes about the Buckeyes basketball program.
"I like the style (Ohio State's) play and my relationship with Coach Dickerson," Walker said. "Both he and Coach Matta are recruiting me. They call whenever he gets a chance to, you know how the rules are now a days, so when they get a chance they call."
Walker said current Ohio State big man Jared Sullinger is a player he looks up to, as both had recent interactions on Twitter Sept. 6. When Walker contacted Sullinger to update him on his recruitment, the current Buckeye told Walker "you will be in love" when he sees Ohio State's campus.
"I like Jared's game a lot," Walker said. "Now he can play outside and inside so it is going to be hard for anybody to stop him. He can shoot now, too. I talked to him on Twitter. He is someone I look up to.
"I want to visit (Ohio State) as soon as I can," Walker continued. "I would take an official visit there. I am going to try and do it the next few weeks. I'd like to get up there and see everything."
Though Walker has two more high schools seasons before getting to college he admitted talking openly with coaches recruiting him about the potential of being a 1-and-done at the next level.
Florida's Billy Donovan reportedly told Walker that he has the potential to raise his draft stock that high in only one year in college. Matta, who has had a long list of 1-and-dones during his time at Ohio State, told him the same.
"That's something that's in my mind. I feel like if I have a chance to go one-and-done I am just going to take it," Walker said. "He said he thinks I have the ability to be one-and-done also and he was just telling me about their program and everything. He said he is OK with it."
Walker plans on seeing through all of his options. After all, he has all the time in the world before he will be under pressure to make his college selection.
For now, Walker is content playing hard and watching the offers come in.
"I think rankings are rankings. Just to be high, to be top ten on every site, it feels good," he said. "I worked hard all the time. I worked at it every day. Sometimes even twice a day. I just really played hard and worked hard."
It's already paying off dividends even Walker couldn't have imagined.
