Jaguars' Myles Jack will make more of an impact in second half of season

JACKSONVILLE, Fla. -- Got questions about the Jacksonville Jaguars? I’ll answer the best one every Saturday morning. Submit your questions via Twitter to @ESPNdirocco. Please use the hashtag #jagsquestion.

There were a lot of good questions, but unfortunately I can’t answer them all.

@ESPNdirocco: I think Jack will have more of an impact later in the season than at the beginning, mainly because he's going to miss all of OTAs. That is invaluable time for a rookie, and while he'll be able to keep up via his iPad there's no substitute for being on the field and in the meeting room. Jack is starting out learning middle linebacker, though he also will learn the outside spots, and I think he will be the eventual replacement for Paul Posluszny, but that's not going to be in 2016. Posluszny is still the starter there and coach Gus Bradley said he still sees Posluszny as a three-down linebacker. Jack's playing time should increase as the season progresses, and as he becomes more comfortable he should make more plays. As for his knee, nobody knows if - or when - Jack will have problems. Could be next week or next month or four years from now. The Jaguars can't worry about that.

@ESPNdirocco: I don't think it would be fair to put any statistical expectations on Blake Bortles in 2016 after he set franchise records for completions, attempts, yards and passing touchdowns. He may never come close to those marks again. The most important thing for Bortles is to cut down on his interceptions (35 in two seasons) and increase his completion percentage (58.7). I think it would be disappointing if Bortles threw more than 11 or 12 interceptions and his completion percentage wasn't 60 or better.

@ESPNdirocco: Don't forget fourth-round pick Sheldon Day. He also plays 3-technique defensive tackle along with Jackson, Sen'Derrick Marks and Michael Bennett. I expect Jackson to be the starter there and Marks will be a significant part of the rotation. Bennett and Day also will get reps, though how many will depend on injuries and the game situation. Jackson and Marks should be on the field together as part of the Jaguars' lightning third-down package along with Dante Fowler Jr. and Yannick Ngakoue. Jackson can play defensive end and I can see the Jaguars using him there in some formations but not on a regular basis.
