LB Myles Jack
As one of the only players left from the 2017 Jaguars AFC Championship defense, Jack is facing a lot of pressure to be the leader of this young and somewhat inexperienced team. At 25 years old, Jack has often been overlooked as one of the better linebackers in the league.
He finished with 66 total tackles last season which was a drop off from his 107 in 2018 due to injury. He played in only 11 games last year which makes his need for a big season that much greater.
But the Colts will have to keep their eyes on him at all times in the middle of the field, especially when Philip Rivers looks to the crossing patterns.
