Jaguars offensive coordinator Jedd Fisch believes rookie quarterback Blake Bortles continues to pick up the offense at a quick pace.
Fisch spoke to reporters prior to Tuesday's practice.
"Blake keeps getting better in understanding the offense," Fisch said. "His knowledge base is improving, so he can play faster. He can make some corrections on the fly. He can make some adjustments."
Fisch pointed out two occasions in which Bortles made a proper adjustment in Thursday's preseason game at Chicago.
The first came on a 16-yard completion to Kerry Taylor on 3rd-and-5.
Bortles then impressed many with his 29-yard pass to Taylor later in the game. On second-and-1, Chicago loaded the box with defenders. Bortles checked to a pass and went through his progressions to find Taylor down the left sideline with an accurate throw.
"He did a good job of checking a play and throwing to Kerry Taylor for a 30-yard gain on the left sideline," Fisch said. "That shows a guy with great confidence. That part of it is fun. ... He's throwing the ball with a little bit better velocity. Maybe using his lower body a bit better."
Bortles has completed 18-of-28 passes for 277 yards in the preseason.
Fisch also complimented starter Chad Henne's performance against the Bears. Henne was 12-of-17 passing for 130 yards and a touchdown.
"He was able to move the ball with great tempo," Fisch said. "We were able to extend some drives where we didn't in the first game. ... I thought he threw the ball well. He continues to throw the ball confidently and rip it in there with some good velocity."
