Some could argue the fact that without a good offensive line, you can't have a good quarterback or a good team.
Think about it—plays start behind center with the quarterback, and if he isn't given enough protection, then the play will end with either a sack or a dead ball.
David Carr's first few years as a Houston Texan were miserable and unproductive. Why? He was constantly getting sacked and didn't have the opportunity to show off his true potential.
It's a lot easier for a running back to work with a less than average O-line—all he needs is one hole and he's gone.
Either way, a talented and young offensive line can help any team produce positive yardage and make a team a winning one.
Let's take a look at the five offensive lines that allowed the fewest sacks last season: New York Giants, Indianapolis Colts, Atlanta Falcons, New England Patriots and New Orleans Saints. All of those teams have some of the better quarterbacks in the league.
This is because they have time to develop the offense and don't have to rush themselves. Rushing leads to mistakes, and mistakes lead to turnovers. In some instances, turnovers lead to losses.
