The Jaguars sport one of the NFL's most impotent offenses and after the latest hard-to-watch showing against the Titans on Thursday night, the team has fired offensive coordinator Greg Olson, according to ESPN.com's Dan Graziano.

Meanwhile, the man who hired Olson, Gus Bradley, remains gainfully employed despite a 14-41 record since taking over the Jaguars' head coaching job in January 2013. That record, by any reasonable measure, is grounds for termination. But owner Shad Khan said Thursday, following the team's 36-22 loss to Tennessee, that there won't be a head coaching change.

That's bad news for Olson, who was hired in January 2015. In his first season, Blake Bortles threw for 4,428 yards, 31 touchdowns and 15 interceptions, and young wideouts Allen Robinson and Allen Hurns combined for 2,431 receiving yards and 24 touchdowns.

But 2016 has been a much different story. Bortles, who has 12 touchdowns and nine picks, has been bad, ranking 27th in Football Outsiders' QB efficiency metric, only ahead of names like Ryan Tannehill, Blaine Gabbert, Ryan Fitzpatrick, Joe Flacco and Brock Osweiler.

Someone had to be the fall guy, and Olson drew the short straw.

The development comes a day after Bradley said he wouldn't be firing any assistants, according to ESPN.com.

Meanwhile, it's unclear if anyone can fix Bortles, who concedes that he's as puzzled as anyone by how consistently bad he's been.

"It's hard for me to sit up here and answer this for you guys," the third-year quarterback said after Thursday night's defeat, which dropped the Jaguars to 2-5 on the season. "You guys know everything I'm going to say, and I don't know. I tell you the same stuff every week. It's difficult."

A big culprit has been Bortles' mechanics, which is obvious here:

Despite the season-long struggle, Bortles will continue to play.

"I firmly, firmly believe in Blake Bortles," Bradley said at the beginning of the week. "Without a doubt. I think it was a challenging day yesterday about some of the situations we were in, but as far as the competitor ... and what he brings to this team, there is no doubt [about Bortles]."

Benching Bortles fixes nothing, neither in the near term nor beyond. Bradley needs to win now, and Bortles gives him the best chance. Unfortunately, winning has been rare and there's a decent chance that Bradley could be out of a job two months -- and the team could be in the market for its next franchise quarterback.
