“I’m watching you Howie Long Jersey , Focker” tweet from Raiders quarterback Derek Carr? He possibly was reacting to a tweet from earlier in the day, posted on the team’s official account.On Monday, the team worked out former Oklahoma quarterback Kyler Murray in Dallas, Hall of Fame Raiders receiver Tim Brown showed up, and he posed for a photo with Murray.“Just Heisman stuff,” the message with the photo declares, a reference to the fact that both Brown and Murray won the Heisman Trophy during their college careers.While it’s entirely possible that the Raiders are simply doing their due diligence with no intent to draft Murray or Ohio State quarterback Dwayne Haskins, it’s also possible that coach Jon Gruden is always looking to upgrade the quarterback position. Chris Simms Lyle Alzado Jersey , who once played for Gruden, understands the dynamic — and Simms believes that Carr has reason to be concerned. There are apparently still too many former top picks in Oakland. The Raiders already traded 2014 top pick Khalil Mack and are now reportedly discussing trading 2015 and 2016 top picks Amari Cooper and Karl Joseph according to Jay Glazer of Fox Sports.Joseph has been a forgotten man in Oakland this season, buried on the depth chart behind Reggie Nelson, Marcus Gilchrist, and Erik Harris.Cooper has been inconsistent and has disappeared in three of the team’s five games this season. He is third on the team in receiving behind tight end Jared Cook and Jordy Nelson.The rebuild has been on since Mack was traded away. These reports are in the same vein. Gutting the team of Reggie McKenzie picks rather than pay them when their contract is up. And do it now because the feeling that the team is not contending anyway and could potentially yield more to a contending team looking to add talent for the stretch run.Coop could possibly yield a high pick, potentially a first rounder, but more likely a second round pick. Joseph might be able to fetch a mid-round pick.Follow @LeviDamien
