Dan Marino – 1984
Marino is arguably the greatest player in NFL history without a Super Bowl. He achieved everything else that was possible in the sport. He also had a cameo in ‘Ace Ventura’ and was a mainstream celebrity throughout the decade. He won the MVP award in 1984 after a brilliant season for the Dolphins.
Miami’s sole MVP winner threw for over 5,000 yards with a league-high 48 touchdowns. Meanwhile, the Dolphins enjoyed a 14-2 regular season record and many people tipped them for the Super Bowl. But they wasted the best opportunity of Marino’s career, and that’s a shame (via Sportskeeda).
