"I don't really see how [fill in the blank] can go much lower." Though that would make 2002 the third consecutive year for that remark, and third consecutive tie with "If it goes any lower, I'm backing up the truck!" The only drawbacks with those is that they can be "dumbest" for months or even years on end, then suddenly turn brilliant. I'd nominate, "Bulls, green light!" if that story hadn't gotten so sad.
