To be clear, I don't mean to advocate one side's position over another. Just that it didn't strike me as a clear-cut issue.
And in my opinion, fair or not, the NFL had considerably more leverage all along. They could probably not survive indefinitely on these replacement refs, although they could have continued to train them and make them better. They could have pulled refs from the college ranks as they did in 2001 (any idea why they didn't in the first place?) Worst comes to worst, the NFL is probably one of the strongest brands in the nation. They could have withstood this for a long time. As much as people complain or talk about it, the eyes are still glued to the screen. And, over time, the NFL would simply find ways to train and develop a new system of refs.
The refs, on the other hand, need the NFL considerably more than the other way around. That's a $150k+ (I think 170k+ now) per-game check they pull down. And, I do see why unions would be opposed to allowing their members to be fired for poor performances. It just is on the whole, a more nuanced issue. The refs have skills, true. This gives them leverage ability and rights. But it doesn't, and shouldn't, give them the ability to demand arbitrarily what they want, and have it granted. Did they demand too much? I really don't know.
Although in reading over about the resolution, it sounds like the full pension is going away for the refs after all - it will just be delayed, and won't apply for new hires. The backup officiating development crew will be an option to the NFL, beginning in 2013. I think that's something that is just good for the quality of the game. That the NFL wanted this demonstrates a commitment to the quality of the game.
And that the refs were so opposed to that idea sort of throws the sympathy-based-on-$$ angle out the window for me. Maybe their demands were still just on the whole (I wouldn't know), but the NFL here wants to spend a larger sum of money total, to hire more people into their ref system, but the refs don't want the increase in accountability.
It sounds like the refs yielded in a lot more than the league did.
