I'm pretty sure you are correct on the mandatory retirement being a FIFA rule.
But many of these top retired refs could definitely work as mentors, consultants etc.
Found an interview with Collin from back on October 2008 http://goal.blogs.nytimes.com/2008/1...luigi-collina/
It applies solely to delisting FIFA referees and assistant referees; although some federations, like Italy, adopt the policy for their domestic competetions.
In England the "retirement" age for referees is 49, that's why Steve Bennett for example, at the age of 48 was still officiating this season in the EPL.
This is an opportunity for MLS to show support for their referees...
"Gentlemen.. we want you to be the best that you can be.
We are therefore providing referee clinics and possibly games featuring officials who have officiated at some of the highest levels of the game.
We trust that you will take this opportunity to furthen your officiating skills in the hope that someday you too will be able to pass on your wealth of knowledge to the officials who follow in your footsteps".
just a no brainer!
more I think about this, more I think DG and MLS FO is like insecure girl
a bit of flash and cute, but inside, worried about how it is thought of by rest of the world because she thinks she's all that
