Isaac Bruce found a way to reach 1,000 yards multiple times before Warner arrived. In fact, he lead the league in receiving yards with Tony Banks at QB in 1996. I'm not going spend my day looking up more examples as you should be getting the point by now.
Getting back to the original argument, you can't put Edelman and Branch in the same class as Moss, Terrell Owens, Marvin Harrison, Steve Smith, Reggie Wayne, Fitzgerald, Julio Jones, Andre Johnson, Antonio Brown, Chad Johnson, Holt, Bruce, etc because they have more rings than them and played in more big games. That's just stupid talk.
