Jaguars vs. Bills: Trevor Lawrence and other Week 5 studs, 2 duds from London game

1. Jaguars dud vs. the Bills in Week 5: Anton Harrison, RT

Anton Harrison was coming off his best performance of the season in Week 5. However, the rookie right tackle couldn't build on last week's success and took a step back against the Buffalo Bills. Although he wasn't particularly dreadful, he was flagged twice, once for offensive holding and the other one for an ineligible downfield pass. Both times, he nullified gains of 10+ yards.

Now, Harrison is experiencing a learning curve, so his regression isn't necessarily surprising. Growth isn't linear and sometimes rookies take a step back after taking a couple in the right direction. That seems to be the case for Harrison, who just made his fifth career start. Expect a few more days like this followed by a few encouraging performances.

1. Jaguars stud vs. the Bills in Week 5: Darious Williams, CB

For a moment, it looked like Darious Williams was going to find himself in the dud column, having allowed a couple plays on the Bills' first scoring drive of the game, including the Stefon Diggs touchdown reception.

However, Williams has a short memory and got better as the game progressed. In the third quarter, he intercepted a pass intended to Diggs that would've put the Bills within scoring defense had it been complete.

Having gotten the ball back, the Jaguars offense then proceeded to march down to the Bills' end zone on a 10-play, 93-yard drive that gave the Jags a brief 18-7 lead. The Bills struck back with a touchdown of their own but that's beside the point.

The bottom line is that Williams had a few mistakes early on but he came up clutch when the Jaguars needed him the most.
