A one-time top target of rival Washington in 2011, Peters will end up playing his college ball in Pullman.
"The coaching staff was really good, the team was really good, coach (Ken) Bone has been successful everywhere he's been at, they have both majors I really want to pursue, they need a big man, and I feel like I can really go in there and be an impact player because they need a rebounder and a presence down low," Peters told Scout.com.
Peters credited his official visit to Wazzu as one of the reasons he's going to Washington State.
"The visit was really good," he said. "I loved the visit. I mean I felt like part of the team when I left the visit."
Another big reason for Peters choosing Washington State was his relationship with the coaching staff.
"Coach Ken Bone, coach Ben Johnson, coach Curtis Allen, coach Jeff Hironaka, all of them, I really had a great time with all of them," Peters said. "I really have a great relationship with coach Allen.
"Coach Bone is a cool guy and has been successful everywhere he's been at. One thing I like about coach Bone is that he's athletic himself, he looks like he can play ball. Coach Ben Johnson does a great job with the bigs."
Peters is looking forward to his future in Pullman and feels that big things are on the horizon for Washington State.
"I think the sky is the limit," he said. "They have a really good team right now and I feel like I can be a force down low to rebound and block shots. What makes it crazier is we may even get a scorer in my teammate 'Q' (Demarquise) Johnson."
