No one really wanted the rule changed in the first place. Initially the coaches voted it down by a huge majority. They only relented when they tried to come up with a way to prevent the Saints / Rams fiasco from happening again. So they essentially are trying to just avoid reversing a call on the field at all cost unless it is BLATANTLY wrong. As in someone got tackled, mauled, hauled to the ground, or hit in the head and knocked unconscious. That's how they are going to call it. Grabs, holding an arm, riding a player out of the play, getting there a little early . . . none of those are going to be considered. Eventually coaches will stop challenging because they know they won't get the call. People may not like it, but that's reality and where we are at.
