Harrison's Contract Extension with Steelers Complete

ESPN.com's John Clayton is reporting that the Pittsburgh Steelers and linebacker James Harrison have agreed on a six-year, $51.175 million dollar contract extension.

The NFL's reigning Defensive Player of the Year will reportedly receive $20 million in guaranteed money, and will now be signed through the 2014 season.

The 31-year old Harrison, entered the NFL as an undrafted free agent from Kent State in 2002 and bounced around the Pittsburgh Steelers and Baltimore Ravens' roosters before becoming a full-time starter for the Steelers in 2007.

Although this is a nice deal for a former undrafted free agent, his guaranteed money is exrtremely low, when you look at pass rushers Dwight Freeney and Jared Allen both received $30 Million guaranteed and Albert Haynesworth got $41 Million guaranteed. Considering his impact to the team and his defensive player of the year status the Steelers certainly got themselves a steal on this contract.

Over the last two seasons, Harrison has started 31 games, made 199 tackles, snarred a pair of interceptions and registered 24.5 quarterback sacks. Harrison also returned an interception 100 yards for a touchdown in the Steelers' 27-23 win over the Arizona Cardinals in Super Bowl XLIII.
