Former No. 3 pick has his head coach “concerned” following miserable showing

Yikes!

Blake Bortles enters a crucial fourth season with the Jacksonville Jaguars and, so far, he's leaving much to be desired.

Bortles threw five interceptions during Saturday's practice, including one that was returned by Telvin Smith for a touchdown. According to ESPN reporter Michael DiRocco, it was "one of the worst practices" of the quarterback's career.

Bortles has spent the offseason working on his mechanical issues in an attempt to improve his throwing motion. However, Saturday's practice proved that he still has a long way to go in order to live up to lofty expectations as the team's franchise quarterback and former No. 3 overall draft pick.

"I think anytime someone doesn't perform to what you want to do, you're concerned about it," coach Doug Marrone said. "He's not the only one that's out there. There's some good things.

"We're going to look at it. We're going to look at those plays. If there's any struggle or things we don't like, then obviously we're going to be smart enough to throw that crap out."

Last month, Marrone challenged Bortles to improve on turnovers.

While it's still early in training camp, time may be running out for Bortles. Still, he has the opportunity to live up to his first-round potential with an improved Jacksonville roster in 2017.

We'll see if Marrone has anything to say after Monday's solid performance:

We'll soon see if he can hold onto the starting job.
