With one game remaining in Week 10, Marcus Mariota has posted the highest Total QBR of the week thus far, while Jay Cutler posted one of the lowest of the season. ESPN Stats & Information takes a look at the best and worst QB performances from Week 10 so far in terms of ESPN's Total Quarterback Rating (QBR).

Top 3

Marcus Mariota: 95.8 Total QBR

ESPN Stats & Information

There are no signs of a sophomore slump for Mariota, who completed 19-of-26 passes for 295 yards and four touchdowns with no interceptions in the Tennessee Titans' 47-25 victory over the Packers. It was his third career game with four touchdown passes and his second career game with a QBR more than 95.

Mariota completed his first 10 passes, including a 9-yard touchdown to Anthony Fasano and a 32-yard touchdown to Rishard Matthews, as the Titans became the only team this season to open a game with four straight touchdown drives. The Titans jumped out to a 28-10 lead before Mariota’s first incompletion late in the second quarter. He entered halftime with a whopping 99.2 QBR.

One area where Mariota excelled against the Packers was down the sidelines; he completed 13-of-16 passes for 217 yards and three touchdowns outside the painted numbers. This game wasn’t an anomaly for him: Since the start of Week 5, he leads the NFL in touchdown percentage and ranks third in Total QBR.

Ryan Tannehill: 95.0 Total QBR

ESPN Stats & Information

Tannehill added 7.6 points to the Miami Dolphins' expected scoring margin on Sunday, by far his most in a game this season (previous best was 5.2 in Week 7). He was 17-of-24 passing for the game, and 11 of those completions went for first downs. His rate of 45.8 percent of attempts going for first downs was his highest in a game this season.

Tannehill completed all four of his attempts traveling 15 or more yards downfield Sunday, tied for the most in a game in his career without an incompletion. He also had a completion of 41 air yards wiped out due to a penalty.

Another area where Tannehill found success on Sunday was against a standard pass rush. He was 13-of-16 with two touchdowns against four or fewer pass rushers, including 9-of-9 in the first half. Tannehill had not had a passing touchdown against standard pressure since Week 3 against the Browns.

Kirk Cousins: 91.1 Total QBR

ESPN Stats & Information

Cousins posted a season-high 91.1 Total QBR in the Washington Redskins' 26-20 victory over the Vikings on Sunday. The key to Cousins’ QBR was his efficiency moving the chains. He gained a first down or touchdown on a career-high 51.5 percent of his pass attempts against the Vikings, including 58 percent of his passes on first down.

Many of those first downs were a result of Cousins’ downfield effectiveness, as he completed a season-high nine passes (on 16 attempts) on throws traveling more than 10 yards past the line of scrimmage. Last year, Cousins caught fire towards the end of the season; only Russell Wilson had a higher QBR from Week 10 onward. Is this the start of another hot stretch for the Washington QB in 2016?

Bottom 3

Jay Cutler: 5.6 Total QBR

ESPN Stats & Information

Jay Cutler had a 5.6 Total QBR on Sunday, the third-lowest by a qualified quarterback (at least 20 action plays) in a game this season. Cutler cost the Chicago Bears 8.5 more points than an average quarterback (QBR of 50) would have on the same number of plays, the fourth-lowest mark in a game this season.

Only 39 percent of Cutler’s plays produced positive expected points added in Week 10, the lowest percentage of any qualified QB this week.

Cutler struggled everywhere, but in particular on throws outside the painted numbers on the field. He was 1-of-10 on such throws, the worst completion percentage on such throws in a game for any quarterback in the past five seasons (min. 10 attempts). His only completion outside the numbers came on the final play of the game.

Bryce Petty: 21.7 Total QBR

ESPN Stats & Information

Petty’s first career NFL start had some highlights and more than a few lowlights. Let’s start with the positive. Petty led the New York Jets on a nine-play, 99-yard touchdown drive early the second quarter, which was highlighted by a 52-yard completion (42 air yards) from out of his own end zone to Robby Anderson. That was by far his biggest EPA play (plus 1.2) and set the Jets up for their only touchdown of the game.

However, that pass was Petty's only completion on a ball traveling 10 or more yards downfield, and every other Jets drive ended in a punt or turnover. The most costly turnover (negative-1.1 EPA) was undoubtedly Alec Ogletree’s interception with under two minutes remaining, which sealed the victory for the Rams. Overall, Petty mostly kept it safe on Sunday, with his average pass traveling 5.2 yards past the line of scrimmage, and struggled to keep the chains moving for New York.

Alex Smith: 41.0 Total QBR

ESPN Stats & Information

If you're surprised to see a 41.0 Total QBR in the bottom three, don't be, as Smith's QBR is the highest of any QB in the bottom three since Week 9 of last season. The Kansas City Chiefs had another impressive come-from-behind victory, but it wasn’t necessarily thanks to Smith as the Chiefs won without scoring an offensive touchdown for the first time since Week 9 of 2013.

As seen in the pass chart above, of Smith’s 25 completions, only two of them traveled more than six yards beyond the line of scrimmage. He was 0-for-7 on passes traveling 15 or more yards downfield, his most such attempts without a completion in a game in our database (since the start of the 2006 season).

In addition, Smith was 3-of-9 for 14 yards and an interception on third down, and none of the completions picked up a first down. Smith’s Total QBR on third down was 1.6 on Sunday, his lowest in a game this season.
