Talking about which guys are lazy and which guys work hard is the biggest waste of team there is for football fans. Sanchez could be the hardest working QB in the NFL or the laziest-we just don't know. Other than the rare once-in-a-blue-moon revelations (Vick admitting he never watched film, stuff like that) there's just no information that would let you know where Sanchez' (or ANY NFL player's) work ethic is relative to other pros.
