JACKSONVILLE – The Jaguars went through their 15th practice of 2017 Training Camp Monday.

The Jaguars practiced a little more than two hours against the Tampa Bay Buccaneers at the practice fields adjacent to EverBank Field in temperatures of 89 degrees.

The Jaguars are scheduled to practice against the Buccaneers again Tuesday, and the teams will play a preseason game at EverBank Field Thursday. Tuesday's practice will be open to the public.

Head Coach Doug Marrone spoke to the media Monday, discussing issues including starting quarterback Blake Bortles, middle linebacker Myles Jack and defensive end Dante Fowler Jr.

Marrone's post-practice comments make up a lot of the following notes and observations from Day 15 of Jaguars 2017 Training Camp practice:

*Marrone after practice clarified comments he made Sunday regarding Bortles. Marrone on Sunday gave quarterback Chad Henne first-team repetitions during the second half of practice, saying afterward he looked at Bortles' "pitch count" and decided to rest him. Marrone on Monday said Bortles was removed from practice because he appeared to have a tired arm. "I might have misspoke when I said, 'Pitch count,''' Marrone said. "We do monitor it. I went back and looked at it. His arm looked tired. Rather than push him knowing he was going to get all the reps that we needed for these next couple of days, I just said, 'Hey …' It was my decision. He said, 'Hey, I'm good. I can go.' I said, 'Hey, let's just be smart.''' Marrone said he made a similar decision to pull running back Chris Ivory from team drills Sunday. "I pulled Chris because I thought it was more important for us to be able to practice today and get all reps," Marrone said. "One more day's rest can't hurt when it comes to those situations."

*Marrone said Monday against the Buccaneers was beneficial because Tampa Bay provided different offensive and defensive different looks than the Jaguars saw in dual practices against New England in Foxboro, Massachusetts, last week. "At the end of the day, I think these types of situations are going to help us: get us closer as a team, get us better in what we want to execute, then go ahead and keep finding out what we can do well and what will carry over into the season," Marrone said. …

*Monday appeared to be a good day for Jaguars edge rushers Yannick Ngakoue and Fowler. It was particularly good for Fowler, who appeared to have at least two effective rushes during one-on-one pass rush work. Fowler got pressure rushing against Buccaneers left tackle Demar Dotson, with Dotson winning one early battle in their one-on-one work and Fowler getting past Dotson in their second repetition. Dotson had handled Fowler consistently in the team's dual work in 2016 Training Camp. "I'm happy with his effort level," Marrone said of Fowler. "He gives good effort, and I think he's getting more quality snaps, which is what you want to see from players.  Now, the next thing we need is to just start getting the results, and they will come. It's a little bit of balance working with him.  Sometimes he becomes extremely frustrated because he's not getting the results that he wants right away, but I keep telling him, 'This is what I'm seeing: I'm seeing a guy that's going to be able to play more quality snaps and those things will come.' Right now, he's doing a good job." …

*The Buccaneers are featured this month on HBO's annual series "Hard Knocks," which each year follows an NFL team through training camp and preseason. That means the Hard Knocks film crew is ever-present this week around EverBank Field. Not that that bothers Marrone. When asked on Monday how different it having the Hard Knocks cameras on hand, he replied, "I didn't even notice." …

*Jack worked at strong-side linebacker in base situations for a second consecutive day Monday, and Marrone said the plan is to leave the second-year veteran there in practice this week and in Thursday's game. Jack had worked in the middle in base during the first two weeks of training camp with Paul Posluszny – last year's starting middle linebacker – playing the strong side. Posluszny worked in the middle with Jack on the strong side Sunday. "We're just trying to figure out what's the best combination for us in base downs," Marrone said. "Then we're trying to find out what the best combination for us to go into the season is, as far as who is backing who up." Jack and weak-side linebacker Telvin Smith are expected to remain on the field in nickel situations. Marrone said Jack will call the defense "because he is a three-down backer, no matter where he plays." …
