Oh, well this explains everything.
Just kidding. It doesn't. But Antonio Brown's agent Drew Rosenhaus is providing a fine example of "damage control" in the wake of "Helmet Gate" between his client and the Raiders.
If you need to get caught up on the entire timeline of events between Brown and the Raiders, here you go. The condensed version: The NFL is requiring Brown to wear a new, different helmet this season since his old one does not meet current safety regulations. Brown does not want to wear the new helmet, and he's sitting out until he gets his way.
