Actually, harping on the "advanced age" of the Steelers' D has become a popular pastime over the last couple of years after "Rerun" Sapp popped off with the "old, slow and it's over" bit - including last season. That's how you could really tell who the chuckleheads who didn't know what the hell they were talking about were last season when they continued to echo the sentiment.
