OK, no question the refs have been atrocious. Missed calls, bad calls, letting games get out of hand, etc.
That said, I think the league has the better side of the dispute. The refs are paid pretty handsomely for part time work. The pension issue can be finessed by changing it only for new guys. Few workers outside government even have traditionla pensions now, so I don't see the refs position as being very sympathetic. Obviously, they get some sort of compensation in lieu of the foregone pensions if they do away with them, but to insist on keeping an outmoded pension structure is not a winning argument.
The real issue is the evaluations and the concept of having more officials to bring in to replace those who have problems. They really don't want that, and I can see why, but I also see why it is a good idea.
The locked out refs had a lot of problems with bad calls and embarrassing mistakes as well. The problem is no one wants to give up a top flight position as a college ref for an NFL job that may disappear overnight. So the replacements are not the best available.
I don't know what the league can do under labor law about hiring permanent replacements. If they started doing that, the union would fol dimmediately. Guys like Ed Houchili love the limelight and would eat glass before giving it up.
The league could do more to help the replacement refs. For one thing, they could start handing out big fines to guys who are taking advantage of the situation and delivering cheap shots. There has been way too much of that, and it needs to stop.
There is one ironic side effect. Everyone is talking about the NFL, nonstop. It has crowed out politics, baseball, etc. It's all anyone is talking about, which the league has to like.
