Washington: Kirk Cousins
Oakland: DE Lamarr Houston
With the Redskins giving up 142.2 yards rushing per game (2nd most in the NFL), they need to firm up their defensive line. Currently, their starting D-line consists of Kedric Golston, Barry Cofield and Stephen Bowen. All are eighth-year players and aged 29 or 30, and they make up a sturdy line that isn't playing too well at the moment. Cofield has championship experience from his time with the New York Giants and is the strongest member of this line. However, Golston and Bowen are replaceable.
A Cousins for Lamarr Houston trade would make sense for a few reasons. One, the Raiders need a quarterback; Pryor and Flynn haven't played like franchise quarterbacks. Two, the Redskins could use a young and talented defensive end (Houston is 26 and in his 4th season). And three, the Raiders aren't the brightest franchise in the league. They would give up good, young talent for a young quarterback when we all know that they'll have another high draft pick at the end of the season. Oakland could simply draft Teddy Bridgewater or Marcus Mariota in the first round.
