One of the greats for sure.
Outside linebacker James Harrison was passed over in the 2002 draft coming out of Kent State. He spent the rest of his career making every other team pay for that.http://sports.yahoo.com/blogs/nfl-shutdown-corner/former-steelers-super-bowl-hero-james-harrison-announces-retirement-152755395.html
The longtime Steelers linebacker was 2008 NFL defensive player of the year, and his 100-yard interception return for a touchdown on the final play of the first half of Super Bowl XLIII will go down as one of the greatest plays in NFL history.
Harrison is finished in the NFL, but history will remember him as one of the greatest undrafted players in league history.
