The Dallas Cowboys were a disciplined group in Week 1, as they only committed four penalties against the Eagles. It was the fewest they had in an opener since 2015, which is especially impressive considering the youth and unfamiliarity along their offensive line.
Upon further review, the Cowboys should've added a fifth penalty to their tally. This clip from last Thursday shows left tackle Tyler Guyton throw a doozy of a left punch while he derailed Eagles pass rusher Jalyx Hunt. The hook rocked Hunt right in the helmet and somehow wasn't flagged.
Guyton made the punch look as part of his blocking motion, but the NFL's front office unsurprisingly deemed it as unsportsmanlike conduct and fined him $12,172, per Patrik Walker of DallasCowboys.
