I used the playoff assignments as an example, there are many ways that refs get disciplined and refs get dismissed all the time. There are a few that are currently arguing wrongful dismissal as well. Yes, doing a poor job embarrases the league, which is why they get disciplined. However, the poor job is embarrasment enough, having someone get behind a camera and a mic and go on about it just adds to the embarrasment.
Oooooo, no playoff assignments! There aren't enough playoff games to go around, so that probably doesn't sting a whole lot anyway. If I screw up at my job, I don't not get invited to the Christmas party, I get called out on the carpet. Or if it's really egregious, I get fired. When was the last time anyone's heard of a ref getting fired?
And calling out the refs embarrasses the league more than doing a piss-poor job? Sounds to me like they've got their priorities screwed up. I get that they don't want anarchy, but clean house and then worry about fining people for making comments.
Like I said, find me a company out there what wouldn't take serious issue with one of their employees voicing their concerns in the public vs. doing in behind closed doors.
