As for his name, Walker said it's actually Kevin Chaz Walker and he's gone by Chaz his whole life.
So where did it come from?
"Everyone asks me that question. I just know my mom decided on it," he said.
Walker's hobbies include golf and karate, although his golf game has gone downhill since he got bigger and became more dedicated to football. He's been participating in karate since he was about 4 years old, and two years ago he earned his black belt.
"It's a hobby I like to do," he said. "It relieves a lot of stress."
With Williams still questionable for this week with his lingering foot injury, what's going to happen to Walker when the former starter gets healthy?
Sitake said Walker can play all three linebacker positions, so he may move over to rover linebacker, where Matt Martinez has been playing, or stud linebacker, where Chad Manis has been the starter. Or perhaps Williams will move to rover linebacker and Walker will stay in the middle.
Whatever happens, Walker will still get his minutes, says Sitake.
"That just gives us more guys to work with," Sitake said. "We'll see which lineup will give us the best defense going into each game. Regardless of who's taking the first snap, they're all going to see the field. I feel like I have more than three starters."
