MLS Cup Final (Spolier!)

Well, the Houston Dynamo do it yet again. They didn't really do anything spectacular in this game. They took care of business and kept knocking at the door. Their reward for consistency was winning the game 2-1. Congrats to Houston for winning another title. The questions I'm left with : a) How did Khano Smith not get a red card for head butting Brian Mullan (at least I think it was Mullan; I was at the bar watching the game)? I try to avoid criticizing referees. Too often too much is made out of things they do. But here we are in the MLS Cup final, the title match of the season with what should be the best referee on the field. Head referee Prus was right there to see what happened and yet he only produced a yellow? Since when is a head butt a yellow? I'm all for stretching the rules especially in a title game but I fail to see why that should be done when violent conduct is involved. b) Will Paul Mariner or John Spencer find themselves coaching a new team next year? Just last week on From The Pitch Mariner said that he was ready to take the right head coaching job if it was there. Could New York now make a move for him since moving for the Fire's head coach Osorio doesn't appear to be going anywhere? And what about John Spencer? Yes, rumors are floating around that the Rapids are not about to give Fernando Clavijo the boot despite the team getting worse the last 2 years. Could it be that the Rapids and Dynamo were waiting until after the MLS Cup to make things official? c) Could Garber have asked for any better weather in DC in late November than they had today?
