JACKSONVILLE, Fla. -- Blake Bortles had one of the better performances of his career in the Jacksonville Jaguars' 44-7 rout of Baltimore on Sunday in London’s Wembley Stadium.

Four touchdown passes, no turnovers, and he completed 65 percent of his passes.

That came one week after his passer rating was in single digits before a garbage-time flurry gave him respectable numbers.

Was Sunday just another high point in a roller-coaster career? Is the inevitable low coming in Sunday’s game at the New York Jets?

Surprisingly, there are signs that Bortles might finally be becoming the consistent, efficient quarterback the franchise needs to legitimately contend in the AFC South.

Bortles has completed 63 percent of his passes for 1,218 yards and eight touchdowns with two interceptions in the Jaguars’ past five games. The Jaguars are 3-2 in those games, and it’s no coincidence that the victories have come when Bortles has played well.

Bortles hasn’t been dynamic in those five games. Even though he threw for more than 300 yards in Week 16 and 17 last season, he threw only one touchdown in each. He threw one touchdown pass in each of the first two weeks this season before tossing four against the Ravens.

However, what he wasn’t doing, for the most part, was killing the team with turnovers. He fumbled twice against Indianapolis in the final game last season, but neither turnover led to points. He turned it over three times against Tennessee in Week 2 -- coach Doug Marrone pegged only one as his fault -- but those turnovers led to only six points.

Turnovers have been Bortles’ biggest issue. He committed an NFL-high 63 in the 2014, 2015 and 2016 seasons and in that time had as many pick-sixes as victories as a starting quarterback (11). Part of Bortles' issue has been that when things start to go badly, he has been unable to snap out of the funk -- and neither has his offense.

Bortles did that with a big bounce-back performance against Baltimore. The Ravens forced 10 turnovers, including eight interceptions, and gave up 10 points in their first two games. Bortles’ 128.2 passer rating was the second-highest of his career, and it was just the third time he has thrown four TD passes in a game.

“I think there's a bit of a stigma around Jacksonville, kind of the, ‘Here we go again’ type of thinking, and I think this group is different,” Bortles said. “I think the guys handled it differently. I thought the locker room handled it differently. I thought Doug [Marrone] was different about it, and never once did I feel like that going into this week.

“It didn't kind of have that feel or that vibe to it. It was a totally different thing, and it was kind of more of, ‘Let's go back, let's get on track, and let's get back to playing the kind of football we know how to.’”

But can he do that against the Jets? If he plays efficient, turnover-free football, the Jaguars (2-1) could be off to their best start since 2007, which is the last time they had a winning record and made the playoffs.

“We were very happy with the play of Blake [against the Ravens], and again, it's something that is going to be defined every Sunday,” coach Doug Marrone said. “We see a journey. We're working to get better, but obviously Blake along with this team is going to be defined by what we do on Sundays.”
