Last Sunday's visit to Tennessee ultimately resulted in a 42-39 loss for the Jaguars, but Jacksonville offensive coordinator Greg Olson came away from the game with plenty to be encouraged about from quarterback Blake Bortles.

The second-year player completed 24 of 36 passes for 322 yards and a career-high five touchdowns. Equally important was the fact Bortles didn't throw an interception and led the team on six touchdown drives in Jacksonville's six trips to the red zone.

Olson pointed to Bortles' performance as evidence of continued development from the third overall pick in the 2014 draft.

"When you watch it, there weren't many decisions that you could question," Olson said, per the team's official website. "There have been times throughout the season where maybe he got away with one, where he felt like, 'Boy, that ball could've possibly been intercepted.' You didn't see any of that on Sunday. He's just getting better and trying to get better and feel more comfortable within the system."

Bortles' has demonstrated improvement over more than just one week. Through Week 14, he's thrown 27 touchdown passes, 16 more than his rookie season. ESPN's Mike DiRocco, citing Elias Sports Bureau, notes that Bortles is one of just six quarterbacks over the last 10 years to throw at least 16 more touchdowns than they did year earlier after starting at least 13 games the prior season. Bortles joins Tom Brady, Peyton Manning, Andrew Luck, Tony Romo and Aaron Rodgers on that list.

The 23-year-old Bortles will look to continue his strong season Sunday at home against the Indianapolis Colts.
