Officiating CREWS are just that. They are a crew, put together at the start of each season, and work as a crew all year. Referees, are referees,=. Umpires are umpires. Side judges, etc...... They do not switch positions throughout the season.
I know a lot of people seem to think that because they are not "full time" officials, it somehow makes a difference. This gets brought up every time officiating comes into question. This sport just doesnt lend itself to having full time officials. They work ONE TIME a week, but they spend up to 40 hours EVERY WEEK preparing for, and "working" on the job.
Not sure what other "part-time" professions require the same sort of commitment. And for those who seem to think that making them "full-time" would somehow improve the level of performance, what would you have them do the other 6 days they are not working a game?
They already undergo extensive film study, receive regular and ongoing updates and communication from the league.
The biggest issue isn't with the officials themselves, its what they are being asked to do, with regards to how the league wants the game officiated. If there is one major problem, its the lack of consistency from crew to crew. Making them "full-time", isn't going to change that one bit.
