JACKSONVILLE – Myles Jack knows what the Jaguars want from him, and it's his objective, too.

Jaguars Head Coach Doug Marrone has said multiple times in recent weeks the Jaguars' plan is to use Jack in a full-time, three-down role in 2017.

"That's what my focus has been on this year, and I'm very excited," Jack told Jaguars.com LIVE Wednesday.

Jack, a linebacker and the Jaguars' second-round selection in the 2016 NFL Draft, discussed a variety of topics Wednesday as Monday's beginning of the 2017 offseason program continued to approach. Among them: what he learned as a rookie, and how he believes he'll improve in his second season.

As far as his role, Jack said the three-down, full-time gig is absolutely what he wants.

"I tried to show flashes when I could [last season]," said Jack, who said he has spent much of this past three months in Jacksonville preparing for the offseason program. "But I'm definitely looking forward to more opportunities just to show what I can bring to the table. There were a lot of learning situations out there.

"You're playing against guys you grew up watching. Now, it's Year Two, so you're a little more prepared. You're not as star struck when you step on the field. I'm definitely looking forward to this season."

Jack, considered one of the top players in the 2016 NFL Draft, slipped to the second round because of a knee issue. He played 16 games as a rookie, and while he started 10 of those games. He mostly shared repetitions at strong-side linebacker with veteran Dan Skuta.

The Jaguars released Skuta Tuesday.

While speculation outside the team has been that Jack could start at middle linebacker next season with long-time middle linebacker Paul Posluszny moving outside, the team has not addressed that possibility publicly. Coaches will meet with players beginning next week, at which times roles will be discussed.

For now, Jack's focus has been on preparation.

"I'm here the whole time, so I'll get a good chance to learn the playbook and show what I bring to the table," said Jack, who missed much of the Jaguars' 2016 offseason program because of an NFL rule prohibiting rookies whose schools aren't yet finished with spring classes from participating. "That's my biggest goal is just proving to these coaches that I can be a three-down player, that they can trust me and that everybody on that field can trust me."

Jack said the biggest factor in establishing trust with the coaches is "being consistent."

"That's the main thing – just knowing what I'm talking about and knowing the plays, limiting my mistakes and learning from my mistakes," he said. "I think that's the main thing, is just showing that constant improvement to the point that they're like, 'OK, we can put this guy on the field and we don't have to worry about him.'"
