Am I incorrect in believing the being an NFL Ref in a part-time job? Don't these guys (and now ladies) have other jobs in the off-season? The NFL should make these positions full-time positions. With all of the rule changes, additions, etc. each year, how can you keep up with it part-time? The structure is already in place - Crew Chiefs, etc. But I believe it should become a full-time profession for them, so that's all they have to concentrate on year-round. May cost a little more to employ them, but I believe the level of play calling would improve.
