Coming into week four, the Patriots looked like they finally got things working in their favor as they got their first win of the season against the Jets. The opposite could be said of the Cowboys, who entered Sunday's game off a significant loss to the Cardinals.

But as we saw, the Patriots could simply not hang with all the Cowboys brought on the field.

After promising opening drives from the offense and defense, everything swiftly went downhill for New England. From injuries to turnovers to even more injuries and the benching of Mac Jones, nothing went right for the usual well-oiled machine we've all become accustomed to over the last two decades.

It will undoubtedly be one of the more memorable games in recent Patriots history, but there's more to it than just being remembered for that. It's also Bill Belichick's worst loss as a head coach, suffering the largest point deficit in his 29-year career.

Plenty of jokes were made once the score hit 28-3, as Patriots fans fondly reminisced about the Super Bowl 51 comeback from years ago. But as many quickly realized, this is not the same Patriots team of old. Unfortunately, this is a team that has proven incapable of getting out of holes that they put themselves into, and that's exactly what happened in this game.

Belichick was visibly upset throughout the afternoon, with the camera panning to him after Mac Jones threw a pick-six before halftime.

Now that the Patriots enter the second month of the season with a 1-3 record, it will be interesting to see what transpires over the next week.

Will there be more changes made to the roster?

Will Bailey Zappe remain as the quarterback moving forward?

Could a big trade be on the horizon to help improve the team this season or set them up for next year?

There will certainly be a lot to pay attention to over the next several days. But one good thing to remember, if you're still able to have any sort of optimism after this game, is the next two games are very winnable. Playing the Saints at home and then playing the Raiders on the road, the Patriots could easily stack back-to-back wins to put them back on track.
