In all good concience, I could not support a boycott or a walk-out. We go to games to show our support of the team. To me, that means the players. I don't go to support the owner, the coaches or the water boy.
Sorry, but when my team (the players) run onto that field to play hard under ridiculous coaching, I thnk that most of our players are doing their best and I want them to know that we support them.
It's kinda like being against the Iraq war but still sending care packages and supporting the troops.
