Marino was, most likely, not winning a ring that year, although I'm confident they would have won a conference title. They were a good team, one of the last really good Dolphins teams, in fact. And they had a succesful season, despite losing their starting backfield by the middle of it (losing Keith Byars that year really hurt). Marino was on the top of his game. But the AFC, for whatever reason, was just not going to beat the NFC. Granted, the Dolphins would have had a better shot than the Chargers since Miami would have been playing in their home stadium and there would have been plenty of incentive on Marino's part to grab a ring and on the part of his teammates to win one for him. So it wouldn't have been impossible. They would have been a huge underdog though, and I could easily see the game getting out of hand quickly.
