For the people complaining/wondering why the Bills didn't get a chance to sub on the James White touchdown.
Per ESPN:
"Many fans wondered whether Steratore's crew should have prevented the snap until the Bills had adequate time to sub out their personnel. NFL Rule 5, Section 3, Article 10 requires the umpire to stand over the ball to give the defense "reasonable" time to match a personnel change or a simulated substitution by the offense.
The Patriots, however, didn't change personnel. ESPN Patriots reporter Mike Reiss charted the same 11 players involved in the touchdown play as had been on the field for the previous 41-yard pass to Amendola, and that arrangement is clear based on video reviews of the two snaps.
One angle on the ESPN broadcast revealed that Patriots tight end Scott Chandler started running on the field as a sub, but then returned to the sideline. The rule book defines a substitution as one where the player crosses the numbers on the field, which Chandler did not do."
Pretty clear. If Chandler didn't cross the numbers, then it was the right call.
