They've been making it up as they go along, for several years now. I'm not sure who to blame: incompetent refs, or incomprehensible rules, or what. Probably a little of both. But the result is you see flags and just cringe -- then many times you see the replay and it's just stupid. And I'll say that about calls that go in the Bears favor, all day long. Plus it makes the games longer and takes the wind out of exciting parts. We can all just go on & on. Worst drag on football in a generation.
