Whether by trade or through free agency, the Bills let several prominent players go in their first months with head coach Sean McDermott and General Manager Brandon Beane. Their 5-2 start to the year offered support for their approach to building the roster, but the last two weeks have not gone well. The Bills have been outscored 81-31 and given up 492 rushing yards in losses to the Jets and Saints. Those losses have both come after the most recent veteran was exiled. The Bills traded defensive tackle Marcell Dareus to the Jaguars and coach Sean McDermott was asked Monday if the team’s awful run defense was related to Dareus’ departure.
