OPINION: When Caleb Williams cried after USC loss, what did you see? There's only one right answer.

"It's something that I've been doing since I was young, and now on a national level being able to try and share that awareness with the public. Me doing just what I did on Saturday, even though it was far from what I was trying to do, it showed and spread that kind of awareness."
