Williams made the announcement on Wednesday at Sandy Creek High School.
Rated as the No. 13 receiver prospect in the nation for the 2012 signee class, Williams is a 6-4, 200-pound rising senior who said he chose Auburn over Ohio State, LSU, Miami, Alabama, Florida and Tennessee and he had scholarship offers from numerous other programs.
"Auburn is all about family and that is very important to me," the Sandy Creek High School standout told Inside the Auburn Tigers.
Williams said he is looking forward to playing for Auburn wide receivers coach Trooper Taylor because of his ability as a coach and his personality. "He is a lot of fun to be around," the receiver says. "He is real funny and real loud. He told me they need a big, physical receiver they can get the ball to in their offense."
While his relationship with Taylor is a very good one, he added that it's not just the wide receiver coach that has him feeling good about the Tigers.
"Usually you can only talk to your position coach, but I can go down there right now and sit in the defensive coordinator's (Ted Roof) office and have a good conversation with him," he said. "It just feels like family and they treat me like family. It's just that feeling you can't explain."
With his mother and aunt at his side and close to 20 other family members present, Williams said it's just a special day for everyone involved and he's glad to have the support of so many people.
"I have been waiting on this day a long time," Williams said. "I have been wanting this for a long time, since I was a freshman in high school. It means a lot to me."
A lot of players have talked about building towards the number one class in the country in recruiting and Williams is no different. Saying he's ready to help out with guys beginning today, he noted that Zeke Pike has been one of the guys he's leaned on and gotten to be friends with.
"I just got off the phone with Zeke 10 minutes before I walked in the room," Williams said. "He was just telling me that we're ready to get that crystal ball."
Scout.com recruiting analyst Chad Simmons has this take on the prospect. "Williams is a very good outside receiver and he continues to get better. He is not a strong route runner and he can catch the ball a little more consistently, but he has a lot of tools to like. He gets good separation down the field, he gets the ball well at its highest point, and he has shown the ability to out-muscle defensive backs for the ball in traffic."
Williams was a standout at the 2010 MVP Camp in Auburn and the 2011 MVP Camp in Atlanta.
A three-sport athlete who competes in basketball along with track and field, Williams said he likes Auburn's offense, which averaged 41.2 points per game last season as the Tigers finished 14-0 as the BCS national champion. "I like how they know who their playmakers are and how they are going to get them the ball," he said.
With offers from across the country and coaches still going to call and try to convince Williams that their school is better, he said as far as he's concerned he's done with recruiting and ready to focus on his senior year.
"I'm going to say it like this, if you have a girlfriend and you got engaged you wouldn't want her going to see other boys," Williams said. "I'm committed to Auburn. I'm not going anywhere else. I'm going to focus on my school and football."
Williams said that he is interested in majoring in criminology and has an ambition of becoming an FBI agent.
