One cannot tell from the clip about the timing of the substitution, but the center is over the ball. Maybe Free Shoes U had run in a late sub. What normally happens is that an official places the ball down and then moves into his position.
If all the officials are in their normal position, then the closest one to the ball is in the backfield. Getting over the ball in that situation is pretty tough. Holding up the snap, in compliance with the rule, is the operative principle here.
i watched the game....the official did nothing to inform Winston what was happening, just got in his way and interfered with him during the waning moments of a tight game...you may not agree with Winston’s actions but the official was incorrect as well...and for the record I wanted BC to win the game...
