It’s not very often that a player in the NFL actually goes AWOL before a game simply because he is unhappy with something related to his football team. Players don’t go AWOL all that frequently, but when it does happen, there’s usually a pretty serious reason behind it.
Pittsburgh Steelers wide receiver Antonio Brown cost himself a football game, seemingly, because he doesn’t get his way as much as he would like to. Or perhaps, as he might feel, because he is being undervalued and underappreciated, either based on how a teammate or coach might treat him or how they might value another player in relation to himself.
