JACKSONVILLE – He doesn't know for sure it was the right approach.

But here's what is certain about Head Coach Doug Marrone when it comes to how he prepared the Jaguars for the 2019 season:

He believed change was needed, and he can live with making that change.

"I don't think I regret that part of what I did," Marrone said Tuesday morning as the Jaguars (4-7) began preparing to play the Tampa Bay Buccaneers (4-7) at TIAA Bank Field Sunday at 1 p.m.

Marrone, in his third season as the Jaguars' head coach, discussed multiple issues during his Tuesday availability. Perhaps most notably, he revisited his approach to the preseason and training camp.

Marrone made multiple changes to the camp schedule to have the Jaguars team healthy and fresh entering the season. He also opted against playing most starters in the preseason except for a Preseason Week 3 game in Miami. He said at the time and reiterated Tuesday the moves were in response to a 2018 season in which the Jaguars struggled throughout with injuries.

"I've been criticized even within the organization of how the team was, and how I trained the team," Marrone said. "But I go back to I make decisions based on obviously things that have happened. Last year, with the injuries and everything we had, I went out and researched a bunch of other teams and what they do."

Marrone said he made a "conscious decision" to change the approach.

"I think you always have to find ways to get better," he said. "You're going to look at what other people do. You're going to look at all this other stuff – whether it's soft tissue, training all that stuff. I went out and I worked my butt off to do that."

Marrone said while he doesn't regret his decision, he said he can't say he won't regret anything about the situation.

"Now, am I going to have regrets? Or do I have regrets?" Marrone said. "Right now, my moment is not to look back and say, 'I should have done this or should have done that.' Right now, I look at it as 'Hey, what's the best job I can do now?'

"Make no mistake: When you don't win football games, there will be a lot of things I look back on and say, 'Well, gosh, if I would have done this or done that …' I think if you don't do that … I think that's poor character when you can't admit to those things."

Marrone later in the media availability was asked to clarify the comments he made saying he had been criticized within the organization.

"I'm not going to stand up here and lie, but I'm also not going to make this thing a huge story," Marrone said. "I'm just telling the truth. That's just how it us. But you know what, though? Just to add that: That's not the first time it's ever happened to me, and I'm sure it's not the first time it's ever happened to anyone in my position. That's not unnormal.

"What's probably not normal is me saying, 'Yes, that it happened.' But like I said before. I don't have a lot of secrets. I'm really boring. I don't have a lot of [stuff] to hide.''
