Wide receiver: Jordy Nelson, Packers, and A.J. Green, Bengals. I hyped Nelson as a sleeper before the season, and he has delivered with 465 yards and four touchdowns. Green, the fourth pick of the 2011 draft, didn't sneak up on anyone, but it's surprising he has been this good (453 yards and four scores) as a rookie with a fellow rook at QB, an abbreviated training camp and no offseason workouts. Honorable mention: Steve Smith, Panthers.
