Pipe down, fan boi. It's called being a critical reader and all.
It's an interesting idea for choosing playoff refs but it seems unlikely that you'll get consistent ratings game to game. Chances are, if you win, you'll like the crew. If you lose, not so much. Just like around here where ref threads only appear when we lose. So by season's end, the highest rated crews are by winners. If you're 0-17, you hate everyone. By mid-season, if you're reffing a winning team's game, are you more likely to want to please that team who's more likely to win if it means you'll get a higher rating and promoted to the post-season where you could see this team again who helped you get there? If refs have biases and feelings like so many here claim, why would you create a system where ref crews and teams could conspire to be buddy-buddy in a mutually-beneficial relationship? Gotta think these things through but knee-jerking is easier.
The real issue that needs to come from the NFL is what their standard is on how close or loose games should be called. Full time refs can also undergo full time training so that standard can be met across crews. We all want less penalties but let's be real; fans will never be happy. Call less penalties and fans will whine that officials don't make calls for their team on purpose. It's lose-lose for refs anyway so hopefully the NFL can publicly address it and go forward with it from there. Tweak as necessary.
