JACKSONVILLE, Fla. -- Jacksonville Jaguars owner Shad Khan has come out and thrown his support behind GM David Caldwell and Gus Bradley despite the franchise's struggles in the third year of the rebuild.

During an interview with NFL.com's Connor Orr, Khan said he is committed to taking a long-term approach and still has patience with what Caldwell and Bradley have done.

"I think if you look at metrics, Blake [Bortles] is a second-year quarterback and I think he's doing much better, quite frankly," Khan said in the article posted Tuesday night. "I think there is a lot of work to do, and Gus and Dave Caldwell have done a lot of heavy lifting. We're to the stage now where we'll be seeing some of the results.

"I'm very, very optimistic and believe in what they are doing. It's frustrating and maddening at times, but if you know football, regrettably it's the right thing to do."

That doesn't sound like an owner who is considering making a coaching change. The Jaguars are 1-5 after four consecutive losses, and Bradley is 8-30 during his tenure in Jacksonville.

ESPN.com's request for a statement from Khan regarding his feelings on Caldwell and Bradley through his spokesman was turned down on Monday. Khan is expected to speak publicly in London this weekend sometime before the Jaguars' game against the Buffalo Bills at Wembley Stadium on Sunday.
