The video showed that the officials got the call right. It may have been a half yard short instead of a full yard, but video showed that it was not a first down.
That said, regardless of whether the call was correct or not, that behavior is never warranted imo. No excuse can be made for endangering people - be it coaches, players, or other fans. You know that there had to be some fans in the stands who were injured in that atrocity.
Unfortunately you are correct. There were a few other calls that were bad, certainly the fumble return, but we were so close anyway. Jones should have held on to the ball, maybe Tillman could have jumped just a bit higher, maybe Milton should have been aware of the clock.
