The Steelers officially announced Polamalu’s retirement on Friday.
Polamalu has played in the league for 12 seasons and has been named to the Pro Bowl eight times.
"It's all about family," Polamalu told Scout. "I live here in Pittsburgh now, and since the end of the season I've had a chance to enjoy my family on a level I never had before. It was awesome."
The 33-year-old played 12 games last season for the Steelers, recording 69 tackles and making one fumble recovery. In his career, he started 142 games and made 32 interceptions and 778 tackles.
Polamalu was a first-round draft pick by Pittsburgh in 2003 and won two Super Bowls with the team. He told Scout that he "did not seriously consider playing elsewhere."
"Thirty-three is obviously significant because of Christ being 33; and 12 years, 12 apostles," he said. "I'm not superstitious by any means but I always thought that if I played 12 years and retire from football at 33 and give my life and give my body and give my blood to this game, I think that would be a pretty significant landmark in my life."
In March 2014, Polamalu signed a three-year extension with the Steelers. He missed four games last season due to a sprained knee ligament. - Molly Geary
