It doesn't matter how good a player can play if they only set you back in the end by not following the rules.
Randy Gregory had 3 penalties alone in this game, enough to cut him in my opinion. The Cowboys are the worst in the league in penalties.
The 49ers started to get sloppy in the second half and the Cowboys had several chances to make the comeback, but they ruined it for themselves. Though the Cowboys were able to hold the Niners to field goals the rest of the first half, their penalties continued to kill nearly every opportunity they had to make something happen against the 49ers, which they did get. Kyle Shanahan and the Niners obviously did their homework on the Cowboys as the Niners were able to score on them on their opening possession. Has no one taught the Cowboys the rules or has no one taught them to follow them? Reactions: A mess of a game for the undiscliplined Cowboys
