JACKSONVILLE, Fla. — Jacksonville Jaguars quarterback Blake Bortles is heading back to California after the team’s three-day minicamp concludes on Thursday.

Not for sun and fun, though.

Bortles said he is going to spend roughly a month in Los Angeles sharpening his footwork and mechanics with personal throwing coaches. He spent more than two months on the West Coast earlier this year in an attempt to bounce back from a disappointing 2016 season.

“February, March, April it was mechanic-based,” Bortles said Wednesday. “Let’s fix this, let’s make sure it’s sustainable and can remain consistent, whereas now I think I’ll go out there with some more descriptive things: Here’s what I felt like I struggled with footwork-wise and throwing this route. Here’s what I’d like to get better at. Here’s something that was new, I’d like to just rep it.

“I think it’ll definitely be a little more kind of dialed in.”

Bortles appeared to have a breakout season in 2015 when he set single-season franchise records for passing yards (4,428) and passing touchdowns (35). While he spent nearly two months at 3DQB in Los Angeles working with coaches Tom House and Adam Dedeaux after the 2014 season ended, Bortles remained in LA just six days after the 2015 season, choosing to stay in Jacksonville to throw with his receivers at a local high school.

Bortles completed 58.9 percent of his passes for 3,905 yards and 23 touchdowns last season, but suffered 16 interceptions (three of which were returned for touchdowns). His mechanics, which he had worked hard on improving the previous season, deteriorated to the point where even his college offensive coordinator didn’t recognize his former quarterback.

The entire season turned into a mess. Offensive coordinator Greg Olson was fired on Oct. 29 after the Jaguars’ embarrassing loss to Tennessee in a nationally-televised Thursday night game. Head coach Gus Bradley suffered the same fate after the team’s loss in Houston on Dec. 18.

The Jaguars finished with three victories — the sixth consecutive season in which they lost at least 11 games — and Bortles’ poor play was a big reason.

As soon as the season ended, he traveled to California to work with his throwing coaches. At minicamp, there was one noticeable difference in his mechanics: He’s no longer dropping the ball near his waist during his windup.

Jacksonville currently boasts its most talented roster since the organization began rebuilding efforts in 2012, and Bortles knows he has to be significantly better in 2017 — in addition to sharpening his mechanics, he must improve his defensive reads and cut down on turnovers — or his time with the Jaguars will likely be over. He feels he owes it to the franchise to get that done.

“It just feels as though guys are sick and tired of being below average and not being successful when we feel as though we have the ability to be a good team and we haven’t been,” he said. “It’s time to make a change. It’s not going to happen overnight. You’ve got to go do something about it.”
