With one game remaining in the second week of the NFL season, Stats & Info takes a look at the best and worst QB performances from Week 2 so far, through the lens of ESPN's Total Quarterback Rating (QBR).

Top 3

Jimmy Garoppolo: 98.9 Total QBR

ESPN Stats & Information

Garoppolo threw for 234 yards and three touchdowns in the first half on Sunday before leaving the game with a shoulder injury in the second quarter. He started the game strong, going 5-of-5 for 64 yards and a touchdown on the Patriots' opening drive. Garoppolo's QBR at the end of that drive was 99.2, and it did not drop below 98.6 for the remainder of his time in the game. New England led 21-0 when he left with the injury.

Garoppolo was especially effective throwing between the numbers, completing 15-of-19 passes for 200 yards and all three of his touchdowns. Overall, Garoppolo had no turnovers and no sacks to go along with his efficient passing performance. Since Total QBR data was first available in 2006, Tom Brady has only posted three single-game totals higher than Garoppolo's 98.9.

Matt Ryan: 97.5 Total QBR

ESPN Stats & Information

Matt Ryan threw for a Week 2-high 396 yards and three touchdowns in the Atlanta Falcons' 35-28 win over the Oakland Raiders. However, Ryan’s raw production is not the reason he ranks second on this list of efficient QB performances.

After a strong first half (92.9 QBR), Ryan marched the Falcons down the field and into the Raiders’ red zone only to throw an interception on a pass into the end zone with 9:35 remaining in the third quarter. From that point on, Ryan completed all 12 of his passes, including two touchdowns, and led the Falcons on three straight touchdown drives. Eight of those completions resulted in first downs, including three that came on third down.

Overall, Ryan contributed about 13.3 points to his team’s scoring margin above what would be expected of an average QB with the same number of plays (EPA), the most points added by a quarterback in any game this season.

Ryan Fitzpatrick: 92.8 Total QBR

ESPN Stats & Information

Fitzpatrick added a total of 11.7 expected points to the New York Jets' scoring margin Thursday, his highest single-game total in his career since Total QBR data was first available in 2006. His largest contribution came from his passing, especially the deep ball.

Fitzpatrick completed 10 passes on throws 15 or more yards from the line of scrimmage Thursday, the most in any game of his career and tied for the third-most by any QB in the last 10 seasons. Fitzpatrick completed nine such passes in two games against the Bills last season.

As seen in the chart above, Fitzpatrick did most of his damage on the left side of the field. From the left sideline to the right hash he completed 15-of-16 passes for 233 yards.

Bottom 3

Alex Smith: 10.2 Total QBR

ESPN Stats & Information

Smith took four sacks, fumbled twice and struggled with inaccuracy in the Kansas City Chiefs’ 19-12 loss to the Houston Texans. No player in Week 2 cost his team more expected points on lost fumbles than Smith, and only a few took more costly sacks (minus-1.5 EPA).

After Smith’s first fumble on the Texans’ opening drive, his QBR fell to 8.9 and didn’t rise above 10 until there were less than two minutes remaining in the game.

The main issue for Smith was his inaccuracy. He was off-target on 10 pass attempts Sunday, one shy of his most under- or overthrown passes in any game with the Chiefs, and he could not find his touch downfield. After completing five deep passes in Week 1, Smith was 2-of-9 on passes thrown 15 yards or longer downfield versus Houston, and he didn’t complete a throw of that distance until the fourth quarter.

Blake Bortles: 18.5 Total QBR

ESPN Stats & Information

The Jaguars’ first-half drives ended as follows: punt, interception, missed field goal, fumble (by Bortles), interception and end of the half. Despite completing nearly 77 percent of his passes in the first half, Bortles entered halftime trailing 21-0 and with a 7.0 QBR. Bortles finished the game with a QBR of 18.5, his 11th game with a QBR below 20 since entering the league in 2014, the most of any player during that span.

In addition to the slow start, Bortles really struggled on third down, where he failed to complete a pass for a first down in eight attempts and turned the ball over twice. Bortles was able to scramble for two first downs on third down, but overall he posted the worst third-down QBR (0.2) by a player in a game this season. Overall he actually cost his team 0.6 expected points on Sunday; only Smith cost his team more among qualified quarterbacks.

Jameis Winston: 26.4 Total QBR

ESPN Stats & Information

After finishing near the top of the league in QBR in Week 1, Jameis Winston is toward the bottom in Week 2 thanks in large part to five turnovers. Winston's four interceptions on Sunday cost his team an expected 4.6 points, with nearly half of it (minus-2.2) coming on his interception that was returned for a touchdown by Marcus Cooper.

As seen in the chart above, Winston struggled with the deep ball on Sunday, completing 2-of-13 passes traveling 15 or more yards downfield (15.4 percent), including two of his interceptions. His completion percentage on such passes was the second-lowest of the week among qualified quarterbacks, and his QBR of 9.3 on such throws was third-lowest.
