"I just wanted to get it out there, that I'm committed to UCLA," said Knox. "I know there are a lot of big names out there that UCLA wants to get so if I know I can be a part of the program, why not say it."
Knox said he called head coach Karl Dorrell on Monday morning to let him know that it was time for him to be a known UCLA commitment.
"I talked to Coach Dorrell, the head man himself, and then I talked to Coach (Dino) Babers and let him know I was in, the offensive coordinater Coach (Jay) Norvell, and EScott (Eric Scott). They were happy and everyone is all proud of me.
Knox said part of the reason he committed was to recruit the remaining UCLA targets himself.
"I just want to help with the recruiting process, help with Coach Dorrell and their program and help with a couple of the big names."
Knox said Carter's commitment last Friday expedited his own process, which he had been wanting to wait until January to announce.
"After he had committed, I felt like it was the best thing to do," said Knox.
Knox also joins a Bruin class that has five City Section players, a section that UCLA had all but ignored in the final years of Bob Toledo.
"It's a City Section all-star team. We all have City Section pride. Everyone is either first team or second team all-City and we are proud to represent the City," said Knox.
Knox said the UCLA campus being so close to his home also helped make the decision easier, and the ease in which his family can come and watch him play.
"They were all excited that they can come to my games and watch me play," said Knox. "I talked to my grandma, and told her, and she got real emotional. She's happy for me."
With his decision made, Knox said his attention will be now turned to helping the Patriots repeat as the City Section championship, and for Knox, its a chance for him to rewrite the City rushing records and earn his second straight City Section player of the year.
"That's the main thing my dad and Coach Dorrell said. Stay injury free, do good in school and try to win another championship for Birmingham," Knox said.
