James Harrison signed the most lucrative contract by a defensive player in Steelers history last April. The $50 million man, however, is not above the kind of grunt work he regularly performed — Harrison excelled on the Steelers' kick coverage teams — before becoming one of the most feared linebackers in the NFL. "If that's something they would call on me to do, then I would gladly go out there and do it," Harrison said of reprising his role as a heat-seeking missile on kickoffs and punts. "I don't think we're in that dire of a situation yet." The Steelers do have to shore up a kickoff coverage unit that ranked first in the NFL last season but has been gashed for touchdowns in the past two games.
