Help me understand Roll Tide Willie

I do my best to pay attention to all things University of Alabama related. But I have zero idea who this guy is or where he came from. First I heard of him was during the Ryan Williams recruitment and everyone was like oh RT Willie is on it...we're good. And then I see him at practices and hanging with Theo Vonn and Im like WTH....who is this guy.

Is he a Finebaum thing? Tictok? Im at a loss and just want to know how he has been off my radar until the past couple of months.
