Mack Strong was an undrafted free agent who was picked up by the Seattle Seahawks. He played 15 years for them, blocked for three 1,000 yard rushers and held the team record for the longest rush in a playoff game with a 32-yard run in 2005 against the Washington Redskins. He was an NFL Pro Bowl Player in 2005 and 2006.
In Week 5 of the '07 season, Strong got hit several times during a game against the Pittsburgh Steelers. Due to a herniated disk and a threat of paralysis, Strong retired, ending a solid career. (AP Photo/Keith Srakocic)
