5 Cowboys who deserve blame for humiliating loss in Buffalo

3. Sam Williams, EDGE

As stated when discussing DeMarcus Lawrence, the penalties that negated defensive stops became a theme. After being forced to punt on their first two possessions, the Cowboys defense was again set to get the ball back for their offense. This time, they forced a fourth-and-eight and KaVontae Turpin fielded it at the Dallas 24.

That punt ended up coming back, however, thanks to Sam Williams. The second-year defensive end got into the backfield and had a shot at blocking the punt. The problem is that he left his feet and sold out on the block, only to miss the ball. Instead, he came down hard on Sam Martin which resulted in a 15-yard penalty for roughing the kicker.

The defense came back onto the field and this time, they were at the Buffalo 41 thanks to the free yardage. They were unabel to stop the home team after this and Josh Allen ended the drive with an 18-yard touchdown to James Cook — who had an insane 179 yards on the ground and 42 through the air as well as two total touchdowns.

Williams has been a solid pass rusher when he's on the field and there are times he's a weapon on special teams. In this one, he reminded us that he can also get the team in trouble with penalties — something he's done several times this year.
