It is interesting that trenches and Military life are so intermingled. From Napoleon to Now, Modern warfare involves trenches. Who wins in them is debatable, They are trenches after all.
In most wars, the trenches are 100-200 yards apart, sometimes nearly a mile.
In the NFL
they are inches apart.
The NFL Trench warfare is Muscle on Muscle, Weightlifters vs Grapplers. Who wins is almost up to the Judges on 95% of the snaps. A Defender sacks the QB or the RB breaks a long gain. The best Offensive or Defensive lines work together to allow or deny success. The Offense has a number of advantages. Snap and direction is not known to the Defense, whilst the Defense has a 2nd and 3rd line to prevent the Offense from winning.
The Kansas City Chiefs Lines are about to make a transition from what they did in 2012.
A little less Maneuver and a little more Stout on both sides of the ball. The Chiefs seem alright with the run blocking, but wanted better Pass blocking than 2012. Eric Fisher is known as a mauling run blocker and as a College left tackle was passable as a Pass blocking Tackle. An upgrade on Eric Winston? Yet to be determined, but Eric Winston was never going to be the Chiefs Left Tackle either.
The Chiefs face an elite run of Defensive Ends and Outside Linebackers in 2013.

The Defensive line has to hold their own as well. Man on Man, I think the Chiefs are in good shape. A better scheme and the Chiefs 2nd and 3rd lines of defense are superior to most NFL teams.
Bend and Break is over. An "In your face" Chiefs defense is the assumed 2013 prescription for years of suck in the Chiefs scheme.
The Stonewall at Fredricksburgh. The Enemy never crossed that line.
