The Jets defensive line would be unstoppable. DeWayne Robertson, Kris Jenkins, Vernon Gholston, Shaun Ellis and Bryan Thomas would be the second coming of the New York Sack Exchange.
The Lions would have the best WR corps of all time. And I wouldn't even need to let Taylor Swift finish.
Charles Rogers would be a deep threat touchdown machine and a slightly shorter Randy Moss. Calvin Johnson would be the undisputed best WR in the league and Mike Williams would never drop a pass thrown his way. They'd be so good, it wouldn't matter who the QB was. But with Stafford at QB, they'd have at least three 50+ yard touchdown passes per game. There just wouldn't be a way to stop Calvin Johnson and Charles Rogers at the same time. Short passing game, intermediate or deep passing game, the Lions would be money every time Stafford dropped back to pass.
The 49ers never would have had to draft Michael Crabtree? Why bother to take a WR tenth when you have Antonio Gates' separated at birth clone (Vernon Davis)?
The Green Bay Packers would never have an incomplete pass. For Jordy Nelson catches all passes the QB throws. No matter what direction they're thrown. Rodgers could be pressured and throw it into the third row, Jordy would come down with it in bounds.
Every punt kicked by Dustin Colquitt would end up on the opponents 1 yard line.
Mike Nugent would make sure the Jets/Bucs had at least three points every time they got into opposing team territory and didn't turn the ball over.
The Raiders would make the playoffs every year thanks to the team's sheer speed. Other than maybe Detroit, no WR group would ever be able to get any kind of separation against cornerbacks Barry Allen and Wally West and safeties Pietro Maximoff and Jay Garrick.
If they lived up to the hype.
