Don't agree with the notion the game is impossible to officiate.
The rules have made it impossible to officiate, and are in need of a serious adjustment.
Also, the officials, lacking the support of reasonable rules, are just not very good at assessing or having a feel for the game and its situations.
For example, I watched a WJC hockey game last week where the Russian captain, in the penalty box, proceeded to break his stick and complain to the refs, after the opposition scored a PP goal to tie the game. Response he was booted from the game. No penalty was given to the team. The game continued, because the refs realized giving an advantage to one team over the other wasn't needed or in the best interest of the game. Let the teams play and decide the game. Don't be the story.
Last nights game. Throw out Pacman. Assess the 15 yard penalty on Burfict. Play on. Don't move them into extra point area to decide the game.
I know some will argue the rules are the rules. No interpretation necessary. Take a gray situation and apply black and white to it without common sense and you get referees impacting the outcome of enjoyable games beyond what is acceptable.
That was really over the top.
