Joe Montana has offered his opinion on who he thinks is the greatest quarterback in NFL history.

Montana didn't name himself, or even Tom Brady, but rather longtime Miami Dolphins signal-caller Dan Marino.

"Put Marino into today's game where he gets free release ... and his receivers, holy cow, weren't very big," Montana told Men’s Health. "Now these guys are 6'4," 6'5." I think [Marino] is probably one of the most unsung heroes of the game. People don't talk enough about him or realize the numbers that he put up during the times that he put them up."

In Marino's greatest season, 1984, he passed for 5,084 yards and 48 touchdowns. Montana says Marino could throw the football in a way that other quarterbacks couldn't.

"He had a quick release. I had to step into a lot of things to get enough [force] on the ball," Montana said of Marino. "He had the perfect torque of his upper body and strength to deliver the ball quickly at a fast release with accuracy."
