Just hours after the New York Jets completed a trade for a star wide receiver, the Buffalo Bills said not so fast and completed their own trade for a star wideout.

The Bills acquired five-time Pro Bowler Amari Cooper from the Cleveland Browns Tuesday, adding a go-to target on the outside for quarterback Josh Allen to throw to.

The trade follows the Bills' win over the Jets Monday night and ensures their division rival didn't close the gap with their Adams pickup. But what does it mean for fantasy teams? Let's get into it.

Stock up: Amari Cooper

This is the easiest call to make. Cooper goes from maybe the worst quarterback in the NFL to arguably the best. He should thrive next to Allen similar to how Stefon Diggs thrived.

Stock up: Josh Allen

Allen was already a top-five fantasy QB before the deal, but it's hard to argue he won't be better off for adding a true No. 1 wide receiver.

Stock down: Khalil Shakir

Shakir was Buffalo's top wideout by default, so he paced the position in targets. But he trailed tight end Dalton Kincaid, and now he takes another dip in the pecking order.

Stock down: Keon Coleman

Coleman had one fewer target than Shakir despite playing one more game than his fellow wideout. He's the unquestioned No. 3 wide receiver now.

Stock up: Dalton Kincaid

Kincaid leads Buffalo in targets and receptions, but he has just one touchdown and ranks second to last on the team in yards per catch. The addition of Cooper should help, not hurt, Allen's favorite target, by opening up the field for bigger plays.

Stock down: Dawson Knox

Knox finally scored his first touchdown of the season Monday night, but that won't be happening much more this year. He didn't have a major role before the deal, and it won't get any bigger now.

What stock?: Browns players

You can confidently fade anyone involved in Cleveland's passing offense.
