Every year IDP owners of London Fletcher are forced to ask themselves "is this the year he slows down?" Last year's 78 solos, his lowest total this century, would seem to say yes. Of course, then there's the fact that his career-high five interceptions in 2012 helped propel him to a top-five IDP finish, and the fact that the last time he missed a game in the NFL was NEVER. He's 38...and he's London freaking Fletcher.
