Remember that one time in 2014 where James Harrison retired and then came back three weeks later? Well he's still here and isn't making retirement plans, as he has declared that he will return to the Steelers in 2016.
This will be Harrison's 15th season in the NFL and his 13th as a Pittsburgh Steeler. Harrison suited up for the Steelers for 13 out of those 15 seasons, as he spent 2003 in Baltimore as a practice squad member and played for Cincinnati in 2013.
Harrison did fairly well as a situational pass rusher, with 40 tackles, five sacks, and an interception. If Harrison can continue to be successful in limited play time, we just might have to put up with him until he's 40.
Steve Smith decided that 2015 wasn't going to be his last year after all, so I guess the fact that James Harrison is going to come back and play for the Steelers in 2016 is only fair.
