A good offensive line can turn an average running back into an All-Pro.
A good offensive line can also give an average NFL quarterback plenty of time to throw the ball downfield.
And and average NFL quarterback with plenty of time to throw the ball can work with any group of half-decent receivers to develop a dominant passing game.
I'll offer Eli Manning as a perfect illustration of how this works.
I always said, if I’m building a team, I start by finding the best Offensive Line coach in the business, who can tag any ragtag unit of guys and turn them into a dominant offensive line.

You can win Super Bowls with a marginal WR corps as long as the other elements of your offense are in good shape — especially the offensive line.
