ESPN's Adam Schefter confirmed the deal, and reports Dallas will be sending a first round pick back to Oakland for Cooper. And Cowboys receivers haven't made many big plays in their first season without Bryant and retired tight end Jason Witten, the club leader in catches.
Now in the NFL's concussion protocol, Cooper should take over as the top option in a Dallas receiving corps that has struggled mightily this season. Recently, we'd heard rumors that Amari Cooper, Oakland's star receiver, was on the trade block, although Gruden denied knowing anything about that.
The Cowboys' trio of offseason additions - Allen Hurns, Deonte Thompson and Tavon Austin - have combined for 32 catches, 391 yards and 3 touchdowns as the receiver snaps have been split relatively evenly these first seven games.
The Cowboys dropped to 3-4 on Sunday with a heartbreaking 20-17 loss to the Redskins that ended with a missed field goal as time expired.
Cooper has 22 receptions and 280 yards in six games this season, though the vast majority of that production came in just two games (10 catches for 116 yards against the Broncos and eight catches for 128 yards and a touchdown against the Browns). With a 1-5 record and no signs for a turnaround this season, those picks will be crucial for the Raiders' rebuild before moving to Las Vegas in 2020.
Trading first-round picks for wide receivers hasn't worked out well for Jerry Jones and the Cowboys. In 2000, they acquired Joey Galloway from Seattle for two first-round draft choices. Williams was drafted seventh overall by the Lions in 2004.
