No series was more indicative of the Patriots’ flat-footed performance than allowing Singletary to score on a 16-yard run to cap a four-play, 89-yard scoring drive to put the Bills up 27-0 with 1:53 left in the first half. Allen placed a perfect 45-yard pass to Stefon Diggs, who had a step on top defensive back J.C. Jackson, a Pro Bowl selection, up the right sideline. Two plays later, Singletary eluded the entire Patriots defense in reaching the end zone.
