OK, so here's what happened between Antonio Brown and Raiders GM Mike Mayock.
Mayock took issue with the fact that Brown posted a screenshot — with commentary — of a recent fine. That led to a dust-up between Brown and Mayock, one that reportedly almost got physical until Vontaze Burfict restrained Brown to save the day.
Yes, Burfict saving the day. That is Alanis Morissette's "Ironic" playing in the distance, indeed.
