Is the best description I've heard of how an O-Line should work. During his post-game presser I heard Coach Chesney talk about rotating his O-Linemen. His reasons may be two-fold: 1) keep his troops fresh, and; 2) looking for those five pennies.
Both our running and passing games will become more consistent when he finds those five pennies. And while the use of the term "Skill Positions" are often used to describe QB's and RB's, it's the guards & tackles & Centers on both sides of the LOS whose skills are overlooked while they matter just as much.
