They play the games for a reason.
Also, much like the Rams last year, the Packers are tightening up against the run when they need to.
Lambeau is no joke to play in come January. There will be at least a few 9ers who don't adjust well.
I think it will be a tough game as Shanihan is a heckuva play caller, but that's no guarantee of victory.
if the Packers can stymie the run and deal with Kittle, they win. That's a tall order, but LeFleur is also a heckuva play caller and the Packers are executing at a high level at the right time.
