Myles Jack has clearly already made an impression on the Jacksonville Jaguars. Drafted to be the heir to Paul Posluszny at middle linebacker, Jack has already forced the team to move the longtime middle linebacker to a new strongside, SAM, role.
Jack needed just 230 snaps on defense in his rookie season for the Jags to make the change. Even in that brief period, Jack has shown he has more than enough ability to take over for Posluszny.
It will be a big job for the young linebacker. Since joining the Jaguars in 2011, Posluszny has had the most tackles in the NFL.
