Joe McKnight once taught us that being out of shape and actively participating in an NFL practice can lead to very bad times. Despite that very public lesson, the New York Jets' reserve running back has run into condition issues once again. ESPNNewYork.com reported Thursday that McKnight was placed on the physically unable to perform list because he failed the team's conditioning test, according to a source. It's not a good look for McKnight, who's no lock to make the roster as he enters his fourth season with the Jets. The former fourth-round draft pick has proved himself to be a strong special teams returner, but he's never carved out a role on offense. Source: NFL.com
