Troy Polamalu

Pittsburgh Steelers safety Troy Polamalu announces his retirement, after 12 seasons and 33 years of age.

He did so in an interview with the Herald-Standard, where he said he began questioning if he wanted to keep playing… which served as a sign in itself.

“Like I said, what it came down to was definitely family,” Polamalu said. “If I’m in my fourth year, fifth year, even if I’m in my 10th year, I’m playing in Alaska. But when I started this process and started to debate whether I should come back or should I play, that was kind of the sign for me to say, ‘Whoa, if you’re just even debating it maybe you shouldn’t play anymore,’ because what I do know about this game is it takes a lot — a lot — of commitment just to be an average player.”

Polamalu won two Super Bowls with the Steelers and retires as one of the franchise’s most decorated defenders. He played his whole career with the team, during which he recorded 771 tackles, 32 interceptions and 12 sacks.

He was also an 8-time Pro Bowler, an AP NFL Defensive Player of the Year, and 5-time All-Pro.
