Taken with the second overall pick by the Lions behind Bradford in last year's NFL draft, Suh revitalized the Lions' defense with his own record-setting season, becoming just the second player to collect 10 sacks in his rookie year.
His season also included 66 tackles, one forced fumble, an interception, one fumble returned for a touchdown and a starting spot at the Pro Bowl.
Suh becomes the first defensive player to lift the award that is voted on by the fans.
"It's truly an honor, it's the NFL," said Suh. "I'm glad I can take this home to Detroit.
"This was definitely not possible without the help of my team mates."
Bradford, who set a rookie record for passes attempted and completed and led the resurgent St. Louis Rams to a 7-9 record, had been the favorite to claim the honor.
