Best QB ever. To hell with the "best passer" or "best thrower" qualifications.
Absolutely.
I've always hated the crowd that ranks players by the amount of rings they have. While I believe it to be very flawed no matter the team sport, it's even more so for football --- which is the ultimate team sport. It sure isn't men's singles tennis or golf.
If you look at ever QB that's been part of a Super Bowl victory, they were surrounded with lots of talent. How many HOF's did Joe Montana, Troy Aikman, and John Elway play with? While Tom Brady may not end up having played with as many HOF's as those QB's did --- he does play for arguably the greatest head coach of all time and still had more talent and play makers around him during the prime of his career than Marino. Hell, Adam Vinatieri is probably gonna go down as the greatest place kicker in history once he finally retires and he's heavily responsible for several of the Super Bowl appearances and wins Brady and the Pats achieved.
Just the other day, we saw one of LeBron James role players (JR Smith) possibly cost the Cleveland Cavaliers any shot they had at winning a championship this season. If Michael Jordan had role players to count upon like that rather than the likes of Steve Kerr, he likely wouldn't have 6 rings. Fact of the matter is, to win a title every star player has to rely upon some of his teammates to make some clutch plays. If they aren't able to step up, even the very bets players can't win. Dan Marino just never played on a team talented enough to make those types of plays consistently. Even the 1984/85 team that reached the Super Bowl was a seriously flawed one. W/O Marino, that team probably doesn't beat Seattle in the 1st round of the playoffs let alone reach a SB.
Marino typically took what was a largely a mediocre team and raised them to a contender that just was never good enough to then get over the hump due to their limitations elsewhere.
When I think of Dan the Man and the crux of his career (before his physical decline), I don't recall many instances, if any, where he didn't come through in a clutch moment. If the Dolphins were in a position to tie or win late in the game, he usually did what was expected of him. That's exactly why he retired with the most 4th qtr comebacks with 2 minutes or less remaining or OT. I don't recall Marino blowing too many games for Miami. That just didn't happen often.
Marino and the Dolphins fortunes were usually spoiled by their defense and/or special teams. The lack of a competent rush attack certainly hurt too, but not near as much a Miami's usually porous defense.
If the likes of Sam Madison, Pat Surtain, Jason Taylor and Zach Thomas came around about a decade sooner, Marino and Miami would likely have a Super Bowl ring or two.
