Ray Lewis is ready to say goodbye to the NFL, but are the playoffs ready to say goodbye to Lewis? And if so, who are they ready to say hello to? A rookie quarterback, perhaps: At least one will survive the wild-card round, but Andrew Luck must survive Lewis, and neither Robert Griffin nor Russell Wilson can expect his opponent to be surprised by an option-based offense. The Bengals would like to introduce themselves to the second round, but the Texans are looking for a way out of a late-season slump and a comfortable rut. Adrian Peterson is never ready to say goodbye, and he never gets tired of running, even if we sometimes get tired of watching. Enjoy a good thing like the wild-card Lowdown while it lasts; as with Ray Lewis’ career, it may be long, but it isn’t permanent.
