I think things will come out in a trickle this year.
The only two white hats I think might retire this year are Corrente and/or Boger.
Boger's age starts with a six, but he just finished up a season with a playoff. He might want to come back for more.
I wrote five weeks ago that some officials who are thinking about retirement might be holding out to see if the NFL offers them a buyout/retirement incentive/severance payment. If these voluntold buyouts keep happening, officials may not want to announce their retirement until the NFL pays them to go away (nice to be in a job that pays you to retire).
Watch her get assigned a Super Bowl her first year eligible regardless of on-field performance. She has not worked any NY6 games, BCS finals or semifinals, or any major game at the college ranks. Getting the Famous Idaho Potato Bowl and the like does not mean you are NFL material. If you are looking at a LJ, guys like Dale Keller, Derek Anderson, and Chad Lorance were frequently the tops of their conference. Those are who the NFL should be hiring.
Yeah I'm pretty certain Fowler and Symonette did not leave voluntarily. I actually predicted this might happen to them after all of the Playoff Assignments were made an neither Official got any sort of assignment. This was the third straight season for Fowler in Tier 3 and second straight for Symonette. Plus Symonette was taken off of multiple National TV games.
Longson however is shocking as he worked a Playoff game this season and generally at least graded out tier 2 plus he was only in his 6th season. I will be interested to see if he is done Officiating for good or if he shows up in the Pac-12 next season.
