The Las Vegas Raiders invested $110 million into defensive tackle Christian Wilkins last offseason, and thus far, his tenure with the Silver and Black has been disappointing. After breaking his foot in Week 5, Wilkins never returned to the lineup last year for Las Vegas. On Friday, Raider Nation received another disappointing update when the team announced that Wilkins would begin training camp on the Physically Unable to Perform (PUP) list. This means that he is out to start training camp, but can return to the field at any point.
