Harrison finishes his career with 84.5 sacks, 34 forced fumbles and eight interceptions to go along with 795 total tackles. That lasted a little over two weeks before he signed with the Pittsburgh Steelers in September 2014.
Father Time appeared to finally get the better of Harrison in 2017, though.
Harrison's Steelers tenure ended in underwhelming fashion, but he leaves a large legacy in the Steel City and will unquestionably be remembered alongside some of the franchise's greatest players. He returned to Pittsburgh after injuries decimated the team's linebacker group and in his second act became a valuable leader on the field and elsewhere, often including teammates in his draining (and well-documented) offseason workout regiments in Arizona.
But after barely featuring with the team last season, Harrison was released and subsequently signed with the New England Patriots to help them during their run to the Super Bowl. However, he had a change of heart and continued to play on for a few more seasons.
