So what are the main story lines for this Monday's game between Pittsburgh and San Diego? I'll give you two. First, it was supposed to be a fairly rare meeting between two members of that 2004 NFL quarterback draft class, with the Chargers' Philip Rivers going No. 4 overall to the Giants and then being immediately traded to San Diego in the Eli Manning swap, and the Steelers' Ben Roethlisberger, who went No. 11 overall. Obviously Big Ben out again with his knee injury is the biggest key here.
