thats where the game is won and lost, between the tackles. Just look at the Super Bowl. The Giants D-Line destroyed the Pats O-Line and the Giants O-Line also outmatched the Pats D-Line resulting in the Super Bowl going to the Giants instead of the "undefeated" Patriots. (haha undefeated haha yeh that happened). So why not put your money on what will eventually win you games. Wideouts, Quarterbacks, and Runningbacks are just products of their O-Line. Also with the great dominating D-Line that can cause constant pressure will make a poor secondary look like an all-pro secondary. Less time a QB has to throw the more mistakes they will make. Also if all the holes are clogged there's no where for a Runningback to run. Its simple economics win and lose through your lines, instead of wasting and holding your breath on specialty players. If your lines are good your team is good. Simple.
