Referee Roster Changes from 2008 to 2009

We start to look at the new NFL season and wonder which referees from the 2008 season are not head referees in the 2009 season. There are retirements every year, so changes are nothing unusual.

Let's take a look -- Bill Carollo (listed as William Carollo on the game reports) retired at the end of 2008 and became the director of officiating for the Big Ten Conference. Meanwhile, Don Carey is a new head referee in 2009 and he is the brother of NFL referee Mike Carey. So now we can't log the referees by last name -- gotta get the first names to distinguish the Carey brothers... let's see how the statistics look as the year progresses.
