Brock Marion won two Super Bowls with the Dallas Cowboys, but when he signed with the Dolphins as a free agent in 1998, he took on a much bigger role. He started every game he played in Miami as the free safety and never came off the bench. The Dolphins wanted someone who could cover the deep middle and make plays, and Marion delivered right away.

He made his first Pro Bowl in 2000 at age 30, and though he was older, he played some of the best football of his career. In 2001, he led the NFL in interception return yards with 227 and scored two touchdowns on returns. He went back to the Pro Bowl in 2002 and 2003. Those three straight Pro Bowl seasons showed he had become a consistent playmaker in the secondary.

Marion also handled kick returns; in 1999 he led the league with 62 returns and 1,524 yards. He was a reliable deep safety who could also make plays with the ball in his hands, and the return work gave the Dolphins an extra dimension on special teams. His range and instincts helped the defense stay competitive during those years.

The Dolphins released him after the 2003 season in a cost-cutting move. With Miami, he finished with 20 interceptions and 534 tackles. The numbers were strong for a player who arrived in his late 20s, and the three Pro Bowls showed how well he fit in Miami.
