Say what you want about Jay Cutler's quarterback play and Brandon Marshall's production in his first season in the "Windy City," but no position on the field is more key to the Bears' 2012 success than left tackle.
The Bears offensive line has been anemic, especially in pass protection, the past two seasons, taking more years off Cutler's life than his past relationship drama with wife Kristin Cavallari.
New general manager Phil Emery has already provided his franchise quarterback with some life insurance by taking away Mike Martz's headset. However, a change in coordinators cannot entirely fix faulty protection on Cutler's blind side.
Left tackles J'Marcus Webb and Chris Williams will battle for the starting spot. Webb started all 16 games last season, but continuous struggles have opened the door for competition.
Williams started nine games at left guard in 2011, before being placed on IR with a fractured wrist.
The Bears originally drafted Williams to protect the quarterback's blind side. Here is why he will win the job this season.
