The Bills rank 21st in total offense, including 25th in passing offense. They missed Stefon Diggs and Gabe Davis, who combined for 152 catches for 1,929 yards and 15 touchdowns.

That's why Amari Cooper was traded on Tuesday.

Cooper, now in his 10th season, is averaging 80 receptions for 1,134 yards and seven touchdowns per season.

“I think that remains to be seen (how much Cooper can help), right,” Bills coach Sean McDermott told beat reporters via team video. “He was obviously on a different team until a few hours ago. We want to get him in here and familiarize him with our terminology and our system and see how he fits in. Like I said: It's never about a man. It’s about the team and in this case the offense.”

Cooper isn't having his best season, with the Browns ranking 32nd in total offense and 30th in passing offense, as well as an obvious rebuild. He hadn't had a 100-yard game since last Christmas Eve, when Cooper torched the Texans for 265 yards and two touchdowns.

Still, Cooper's 24 catches for 250 yards and two touchdowns are more than any Bills wideout this season.

“On paper it’s one thing,” McDermott said. “At the end of the day, can the person play and help us? That's exactly what we want to see in the next few days. I would hope the answer to all of this is “yes.” We're going up against Amari and we have a lot of respect for him and his game, but again we have players in the team that we're already confident in and he's going to fit into that equation and we're going to integrate him and get him excited. See how here quickly he gets up to speed.

“Again, one player doesn’t save a team. One player does not make a team. It’s about the team.”

The Bills' top four wideouts, Khalil Shakir, Keon Coleman, Curtis Samuel and Mack Hollins, have combined for 548 career receptions for 6,469 yards and 41 touchdowns. Cooper has 691 receptions for 9,736 yards and 62 touchdowns.

He is a No. 1 receiver.

“Everyone in this room before Amari was here had slightly different skill sets,” McDermott said. “So now it's really like this and how it fits in the space and how our system can leverage Amari's strengths to improve our system.”
