The refs should get the call CORRECT, PERIOD.
It'd be nice if the refs got everything right, but sometimes they don't, and not every mistake is reviewable. Pass interference, for example, is not reviewable. Maybe it should be. Maybe everything should always be reviewable, but that's not the way things are currently.On the list of things that are not reviewable are mistakes that go against teams that throw challenge flags gratuitously.
I think that's a decent thing to include on the list — at least as good as pass interference is.
The default result is the call on the field. Reviews are exceptional remedies that are provided only in certain situations. When a coach is a tool about requesting such an exceptional remedy, maybe he shouldn't get it.
If one guy is about to give a homeless guy a dollar bill, and right before he hands it over, the homeless guy says something snotty like, "Yeah, you
better give me that dollar!" ... I don't think it's wrong to pull the dollar back.
When the refs are about to give a coach a replay review, and right before they grant it to him, the coach does something snotty like throw the challenge flag in a fit of
machismo*, I don't think it's wrong to pull the review back.
(*And that's what I think motivated Schwartz to throw the flag. I think it was
machismo. I think he was showing up the refs. "Yeah, you
better overturn that call!")
