Myles Jack, LB UCLA
With the additions of CB Prince Amukamara, S Tashaun Gibson, and DL Malik Jackson in free agency, the Jaguars' biggest hole on their depth chart is at linebacker. As of now, Dan Skuta (ex-Bengal who had just 31 tackles in 13 games played this past year) is starting alongside Paul Posluszny (103 tackles) and Telvin Smith (99 tackles). An upgrade is definitely needed there. In comes uber-athletic linebacker Myles Jack out of University of California, Los Angeles.
Jack has major speed - he was once a running back - which helps him excel in chasing down running backs and getting to the ball from any position on the field. He's considered to be a "downhill runner" who can weave through gaps and rush the quarterback. But, not only does he have the speed to cover running backs and slot receivers, he has the size (6'1, 245) to cover tight ends. Due to his athleticism, some see Myles more as a safety - rather than a LB - and I see my Jaguars taking advantage of this by playing him at SS while in a run defense and LB when defending the pass.
Also, due to no team having a glaring need at linebacker until around the 10th pick -- the Giants -- I would've liked to have traded this pick down to the Buccaneers at the 9 spot to save money and add a draft pick.
