The Raiders sent a group to UCLA on Thursday to workout linebacker Myles Jack according to Matt Miller. Jack is considered a top-five talent in the 2016 NFL Draft, but his stock could fall due to a torn meniscus he suffered during the 2015 season. David Chao, a former NFL head team physician is highly doubtful Jack will be a top pick and thinks he will likely drop out of the top ten picks.
The question with Jack is career longevity as there is no way to replace a meniscus. Instead, doctors can simply take the meniscus out or staple it together. An NFL source called Jack a "ticking time bomb" whose knee could give him several good years in the NFL. But the bone and cartilage are starting to break away so teams are worried how long Jack will be able to play.
If the Raiders believe Jack will return at full health and have a lengthy career in the NFL, they should absolutely select the star linebacker at 14 overall as he is a top talent that fills a need on the defense. Jack would instantly start at inside linebacker next to Malcom Smith and would combine with Khalil Mack, Aldon Smith, Mario Edwards Jr, and Dan Williams to give the Raiders a scary front-seven.
