Former Dolphins quarterback Dan Marino expects one of his passing records to fall this season.Former Dolphins quarterback Dan Marino set the record for passing yards in a season with 5,084 in 1984, but if the league's quarterbacks continue at their current pace this season, Tom Brady, Drew Brees, Aaron Rodgers, Tony Romo and Cam Newton all would surpass his total.

Brady is the current frontrunner with 1,874 through five games, which puts him on pace to shatter Marino's mark with nearly 6,000 passing yards.

Why are so many quarterbacks putting up huge passing numbers?

Marino, now a CBS Sports studio analyst, says the game has changed. The rules limit contact by defensive players and severely penalize many of the bone-jarring hits that made the safeties and linebackers of his era famous. Tight ends and running backs are more versatile, the no-huddle offense is more common, teams throw more than ever and receivers are bigger, stronger and faster.

With all those factors, Marino concedes that it's probably just a matter of time before one of the league's longest-standing major offensive records falls.

"I don't want anybody to break it," the Hall-of-Fame quarterback said, laughing. "There's a lot of guys that are going to have a chance to break it, I'm sure."

Brady's success is in large part due to his connection with Wes Welker, who has a league-high 740 yards receiving and is on pace to gain 2,368 yards. That would shatter Jerry Rice's record of 1,848 yards set in 1995.

Marino likens the Brady-Welker combination to the connections he had with Mark Clayton and Mark Duper.

"They're very instinctive," Marino said. "They've been together for a while now. They understand coverages. Wes Welker probably understands what Tom Brady is thinking at the line of scrimmage."
