I'm for making a point against the board.
I don't agree with those saying it was bad timing because it was a "crucial" game. It wasn't. The bad timing was because the players decided to show a bit of fight and actually put in a performance.
The fans cheering and applauding for the team is great, but the board will just see that as people being happy with things though, and that it's only a minority who are unhappy with them. (It's not a minority who are unhappy with the board of reality though).
Protests before and after the game don't do anything. It's only during the game that the media will really pick up on it and show it live. Banners always hit the screen, as would a walkout during the game.
If it had been the derby, we would have been 2 down (which could have already been several more) and at that point not showing much. Many more would have then gone along with it and it would have had more of an impact.
