Last week the Raiders won a game. That dropped them out of the driver’s seat for the number one overall pick and in order to get it back they would need the 49ers and Cardinals to win another game. That didn’t happen this week, keeping the Raiders’ own pick at third overall.
As for the picks they acquired in trade with the Bears (Khalil Mack) and Cowboys (Amari Cooper), those just keep dropping as those teams keep winning. The Bears have won five in a row and the Cowboys are 3-1 since Coop joined the team, winning three straight.
