Perhaps the most interesting journey to the NFL for a guy who might one day end up in the Hall of Fame, Harrison was on and off the Steelers' practice squad in his first year and was allowed to sign with Baltimore in 2003.
In 2004, the Steelers picked him up after an injury to Clark Haggans. Harrison took this second chance seriously and never looked back.
Since then, he's replaced Joey Porter on the outside and has become one of the the most feared hitters in the NFL. His hits have drawn the ire of the league and the admiration of his teammates and fans.
It really is quite the journey for a guy who now seems like someone who would have been a first-round draft pick. That just shows how fickle things can be at times.
