Paul Bryant's star defensive back announced his commitment to play college football at Washington State Friday morning during a press conference held at his school.
The 6-foot, 175-pounder holds more than 15 offers, but said the biggest factor was the Cougars offered him a chance at some early playing time.
"I just felt like it was in my heart to go there out of all the schools," Porter told AL.com. "All the schools that recruited me did a great job, but something stood out about Washington State. Talking to coach (Mike) Leach, he always tells me I could be a big asset to the team. By committing and coming up there I could get early playing time because he's graduating five DBs in the secondary.
"He said if I come out and do what I'm supposed to, I'd be good."
Porter said he doesn't see his commitment changing from now until National Signing Day, but he plans to take an official visit to Toledo, which just recently offered him a scholarship.
He also plans to make his first visit to Washington State on Jan. 17.
Porter finished with 41 tackles, nine tackles for loss and three interceptions in his senior season for the Stampede, which finished 0-10 in 2013. Porter also played quarterback for Paul Bryant.
Stampede head coach Errol Jones said Porter put himself on the map this summer by going to a number of elite camps.
"He just did everything he was supposed to do to put himself in this situation," Jones said. "He's avery determined person and if he does what he's supposed to, which I have no doubt he will, he's going to have a lot of success out there at Washington State."
He is rated by 247Sports as a three-star prospect and by Rivals as a two-star prospect.
