I agree. Whether or not it's a good rule is a different discussion. It's been in place so that's how it goes. Someone just has sour grapes.
Conversely, in our league our commish messed up and let offensive players get points for defensive plays (tackles after a pick, fumble recovering, etc). It wasn't supposed to be that way and I brought it to his attention before halftime of the first game of the year. He finally changed it after week three, but then changed it back. He goofed up, but left it, which I think was highly inappropriate.
This year he also pushed a trade through a mere hours after it was made because his wife "thought it would have been approved before Thursday, which is when she needed the defense." Again, he skirted rules that have been in place.
That stuff I'd gripe about. Rules that have been in place need to be challenged in the off season, not in the playoffs. And if there are rules, they should remain in place for the season in 99.9% of the cases.
