John "Moon" Mullin of CSN Chicago insists Johnny Knox still has a chance to overtake Roy Williams for the Bears' starting split end job. Mullin says Williams' camp and preseason production is "at zero," while by all accounts Knox has been impressive both on the practice field and certainly in games. Mullin also opines that Williams' "conditioning situation" has "retard(ed) the full-speed work that a receiver can do with his quarterback." Both players should see extensive snaps in the third preseason game.
