At 4-6 on the season, the Oakland Raiders are close to becoming irrelevant in the AFC Playoff race. This harsh reality led to the firing of defensive coordinator Ken Norton Jr. following last week’s blowout loss to the New England Patriots. It now looks like another high-profile assistant on Jack Del Rio’s staff will be shown the door here soon. “Raiders offensive coordinator Todd Downing is under increasing pressure with his unit struggling and is coaching for his job down the stretch,” CBS Sports’ Jason La Canfora reported Sunday. “He is unlikely to be back with the team in 2018 at this point and the situation could come to a head before then.” As much as people want to focus on the Raiders’ defensive woes, that was never really going to be an area of strength for this team in 2017. Remember, Oakland finished last season with a 12-4 record despite giving up north of 24 points per game. It’s yielding just a half of point more on average this season. The primary issue here has been an offense that’s regressed a whole heck of a lot after Oakland parted ways with former coordinator Bill Musgrave following last season, replacing him with Downing.
