2 rulings on the field I felt were not explained by the commentators and I'd be happy if they'd be explained
A. On the 4th down that the Jets did not convert - the camera showed Saleh debating if to throw the red challenge flag. Isn't it a change of possession so it's automatically reviewed so no challenge? After the ref's discussed it and decided it was indeed incomplete, the commentators said that Saleh was about to throw the red flag but the refs told him we reviewed it so it's a waste of your time - wouldn't it be something the ref's are not allowed to say to a coach? I was totally confused
B. Jets had a 3rd down (sometime in the 4th qtr) the bills rushed well and Mike White was flushed out of the pocket and managed to get only 3 yards rushing. A flag was thrown for defensive holding - 5 yards. The refs added it to the end of the play. Isn't an accepted penalty during the play instead of the play, not in addition to the play. Also didn't understand that. What are the rules?
