rmcjacket23: A costly major mistake happens every week and not just to the Ravens. Just listen to Sirius NFL Radio, you can hear it from fans all around the country. And not just fans, there are also previous players, GMs, and others knowledgeable about the game that thinks it needs a major overhaul because of the costly/egregious mistakes. And I am talking about the ones that everyone knows (including the NFL Vice President of Officiating) should have been called or not called..except the ref on the field.
Concerning full-time refs. They can be learning the rules and training the other days of the week, during the season. Doesn't matter about the offseason (The players and teachers have an offseason so why can't they) If they are paid well enough for full time positions it doesn't matter. They can also have training sessions and practice for the new rules each year. There is a lot that can be done here. Also we could get new batches of refs every year like the players. We could have rookie refs that don't get to make the calls but observing and learning. And if they have proven that they are good enough, they can get on the field. That is how you can have full-time Refs. We are just accustomed to the way it has always been done and now that way isn't working so great.
