The championship window can fade fast.
Let's walk through the Dan Marino narrative:
Marino, a Hall of Famer, changed the game as a young player with a golden arm and won Rookie of the Year. He's one of football's all-time greats.
But Marino is better known as the best player in sports to not win a championship.
Marino won the league's MVP honors in his second season, destroyed the Pittsburgh Steelers in the AFC championship and then was flattened by the San Francisco 49ers in the Super Bowl.
The sports world expected that Marino would have plenty of time to return and eventually win it—but he never did.
The title window can disappear quickly in the NBA, too. Just ask Charles Barkley.
Kevin Durant cannot allow this current opportunity with a talented Oklahoma City team to slip away.
Crystal Ball for 2013
Durant will win the scoring title and the MVP award this season.
The Thunder will return to the playoffs as the top seed in the Western Conference and will host the Los Angeles Clippers in an epic conference finals. The Thunder, on the shoulders of Durant, will be victorious in seven games.
Durant will then lead the Thunder past the Miami Heat in the finals and surpass LeBron James to become recognized as the league's most talented player.
He may still be slightly less talented than James, but he's developing at a greater pace and is surrounded by a more complete team.
