Roby said he was taken aback when he saw the figures on his contract and that he ''worked my whole life for that, so it was a great feeling.''
He said the first thing he'd do with his roughly $3.5 million signing bonus was ''buy my mom whatever she wants.''
The Broncos selected the All-Big Ten cornerback with the 31st pick in the NFL draft last month. He was the last of their six-player draft class to sign his deal.
Bradley started all 37 games he played at Ohio State, where he collected eight interceptions and broke up 44 passes.
