All I can say is... if that sub-ref hasn't been fired already... if he ever steps foot onto another football field, he had better wear a different number on his stripey shirt. Otherwise, he may be lynched on the goalposts.
I blame the NFL, not the replacements. The replacements were placed in an almost impossible situation. There's no way that this was going to work. It's one thing to have a rookie official in with a team of experienced officials, but when all of em are rookies and aren't used to the speed of the NFL, it's going to be a clusterfuck. If the NFL would just suck it up and realize that what they pay their officials is worth every penny, they can resuce the reputation of the sport.
As for the replacements on the field; they're making bad calls, can't keep up with the speed of the game and are just plain out of their league. The coaches don't respect em, the players don't respect em. It's like the kids in a school room testing the inexperienced substitute teacher. It's a wasted day in class as the teacher is just trying to survive until the real teacher gets back. The longer this goes on, the worse this season is going to be.
And if the NFL is concerned about player safety as much as they say they are, they'll get the real refs back on the field. Someone is going to get seriously hurt before long, the way the late hits, the blind side launches and post play fights are going.
If the situation isn't settled soon, this entire season should have an asterisk by it in the record books.
