The most logical scenario to me is Banks was suspended for violating team rules (missed practice/meeting). This fueled his anger and he happened to walk across the T in the process. He got called out on it by Hooker, which led to a verbal exchange and Banks started mouthing off about NIL while refusing to do what he is supposed to when stepping on the T. Milton separated them as they were jawing with each other. They said ok we are good with each other and went on their way.
From a 3rd party perspective (a different player), this could all look like it stemmed from NIL. Not all players are as informed as others. Rumors spread, people take sides, tempers flare.
I could be way off, and I probably am, but logically that scenario makes the most sense to me.
