It's funny, but when there are dominant teams, there are a number of people who rail about the fact that they're always seeing the Dallas Cowboys or the San Francisco 49ers or the Green Bay either in the playoffs or in the Super Bowl.
Nobody wants to see teams out of contention showcased in December and January. I'm sure this is something that will be discussed again this off-season.
If there are dominant teams, people enjoy discussing whether that's good or bad for the game, and if there aren't any dominant teams, then people enjoy discussing that.
I don't expect to see them in the top six but I think of all the teams that have come up in previous seasons, I think Manchester City are the biggest club.
I only started concentrating on football as a career when I left school at 18. I played golf for the Scottish and British boys' teams.
I do my own analysis on the teams I am refereeing. I will know some of the personalities, the players who could be difficult customers in a scrum situation, the ones I am going to have to really work hard on early in the game to get what I want.
But then southern hemisphere teams are more skilful than their northern hemisphere counterparts, which means games can be easier to referee.
The decisions I've made have not always been the most popular, but when I look back, I want to know I've played for good football teams.
Do I want to be in St. Louis forever? Of course. People from other teams want to play in St. Louis, and they're jealous that we're in St. Louis because the fans are unbelievable. So why would you want to leave a place like St. Louis to go somewhere else and make $3 million or $4 more million a year? It's not about the money.
I think the one commonality between the two Super Bowl teams I've been on is great, great teammates. I can honestly say that guys in Philly could definitely thrive in New England and vice versa - if you throw out the scheme differences.
