Did Dak Prescott, Cowboys score on controversial goal line dive?

Dallas rolled into New England in an unfamiliar position: as the favorite.

The Cowboys, so long an underachieving clown show of a franchise, are now as legit as any team in the NFC. The Patriots, so long a dynasty, are now grasping at straws as they try to navigate their post-Tom Brady existence.

In a half with more drama than a Netflix series and some stunning reversals, no play was more controversial — and potentially more important — than Dallas quarterback Dak Prescott's dive across the end zone with 92 seconds remaining. The touchdown would have put Dallas ahead, but instead ... well, this happened:

Prescott clearly loses control of the ball, but was it after he'd crossed that mystical goal-line plane? Or was he already losing his grip before piercing the end zone veil? Cowboys fans howled, as expected, but they may well have a point.

The Patriots went into the half with a 14-10 lead, although the Cowboys eventually won in overtime, 35-29.
