Harrison a cap casualty?

In recent memory, the Pittsburgh Steelers have always danced around the NFL's salary cap limit, asking certain players to re-structure their deals (or take a straight pay cut) in order for them to get under that line. It's a similar situation this offseason, and some believe that the club will let most (if not all) of their impending free agents walk as they attempt to finagle themselves out of the situation. As they do so, they may need to make some cuts to their veteran roster.
