Jaguars beat Bills in London, start winning streak: 3 takeaways from Week 5

2. The Jaguars couldn't get after the QB but managed to stymie the Bills' offense

The Jaguars' offense was the victim of self-inflicted wounds but their defense consistently bailed them out. Although they couldn't get after Josh Allen, the front seven contained Buffalo's running game and generally prevented big plays. The lone exceptions were the Bills' scoring drives. In the first one, Darious Williams gave up a couple big plays. Later in the fourth quarter, Buffalo struck down right after Travis Etienne's second touchdown to make it 25-20. But for the most part, the defense kept Buffalo's passing game in check.

Speaking of Williams, he came up clutch with a huge interception — his second in as many weeks — early in the fourth quarter. Josh Allen targeted Stefon Diggs on a deep pass and had it been completed, he would've either scored or put the Bills inside the Jaguars' 10-yard line. Instead, Williams made the play and gave the ball back to the offense. The best part was that the offense took advantage of the opportunity and drove 93 yards downfield to reach the endzone on a Travis Etienne run.

Even though the defense didn't come up with as many big plays as last week, they still keep the Bills away from the red zone when it mattered the most and that's equally noteworthy. You could point out that Stefon Diggs crossed the 100-yard mark. But besides his one touchdown reception, his performance didn't translate into points on the scoreboard.
