The only referees who were HL’S I can think of we’re Cal Lepore and Jerry Seeman. No umpire has ever become a Referee.
Also include Tom White and Dale Hamer (who was with Jerry Markbreit’s crew for many years)
Ben: I´m watching new numbers on officials’ shirts (#144, #145, #148, #149, # 154). Can you give us the name of this guys? They don´t appears in the crews you gave us. Thanks in advance
Any official with a number higher than 135 is an advanced training official who is getting some on-field work.
They don’t show up in the crew lists, because they will only work select preseason games.
Meant to add that to the post, but I threw this together while I was on vacation. The blessing and the curse that is free wi-fi.
