In today's NFL, the players grabbing the most headlines are quarterbacks, running backs, and wide receivers. But according to Michael Lewis' book The Blind Side, the ones who grab the second highest paychecks are left tackles.

In the book, Lewis tries to explain the importance of these anonymous, but essential, offensive linemen. He traces their emerging importance back to the career-ending injury of star quarterback Joe Theismann on Monday Night Football in 1985. More than 17 million people watched as an incredibly athletic linebacker named Lawrence Taylor blindsided Theismann, breaking his leg.

Since most quarterbacks are right-handed, the left tackle's main role is to prevent his quarterback from being hit from behind, unseen. And with the next generation of athletic linebackers and defensive ends, it takes a special person to do it. Left tackles must weigh more than 300 pounds and have long arms to block, but they must also be quick on their feet. Today, teams are willing to pay for such a player. By 2004, the average salary of a left tackle in the NFL was $5.5 million a year. Only starting quarterbacks earned more.

The role of the left tackle is literally to be his "brother's keeper." This is the role that God plays on our behalf, and this should be the role of every player in God's church.
