Ok, here's my take. I've been a rabid fan since the early 80's, so I watched the 12th man evolution from pretty much it's beginning, back when Zorn was flinging the ball around the Kingdome, and Bill the Beerman was a Sunday staple. It all started with the WAVE, something we didn't start (I believe the Washington Huskies started it, but I've heard arguments that some other college team started it and we copied it), but Seahawks fans brought it into the national spotlight, and it started to be copied around the league. Back then, when the Wave was still "cool", it started out as a thing to just get the fans into the game. But I remember getting pissed because they would do it when we were on offense, like that would fire up the team or something. Over time, and gradually at some point, the fans started to realize that it was hurting our offense when there's this damn wave going 'round the dome when our guys were trying to communicate on offense. So fairly soon, Bill would only start the wave when the other team was on offense, and sit on his hands when we were operating on offense. It was around that time that the team realized we were actually affecting the opposing players, and the team took an unprecedented step and rewarded us by retiring the #12 in honor of the raucous crowd. Fast forward a couple years, and the NFL decided that these uppity Seahawks fans should be punished for their fanatical support of their team, and worse, it was creating problems for the teams that brought in the most money (Oh, did I say that out loud? I meant the 'popular' teams). A crowd noise rule was actually approved by the league, and was tested during a game against, if I remember correctly, the Denver Broncos and a whining John Elway. They threw the flag for excessive crowd noise, costing us 5 yards and I remember getting SO PISSED! But I was rewarded with the Kingdome crowd getting twice as loud on the next play. We were gonna flag our own team right back into a safety if necessary. It was such a proud moment! After making our stand that fateful day, that rule kinda flew out the window, never to be seen again. So anyways, over the years, the Seahawks fans have refined the art of opposing team disruption, knowing when to get loud and when to STFU. Now, it's a science for us, and a badge of honor for every fan of the Seahawks. It's become it's own "thing", and every player and coach on our team LOVES it! Such a "real" and huge advantage. I guess my only advice to you, Dolphins fan, is to look up every Dolphin message board or any other social media that is Dolphins-related, and spread this word... and tell them to tell every other fan that they know to spread the word. I think you 'could' make a difference if you do this. Good luck to you guys. I've always kinda liked the 'fins, or at least never held any ill will towards them. I was a big Marino fan back in the day.
