If you haven't seen The Blind Side yet, you may not understand the importance of an offensive lineman.
The offensive line, most importantly the left tackle, protects the quarterback from being sacked and gives him more time to find a receiver to throw to. They also open holes for the running back to run through.

A good offensive line can make a bad team look good, whereas a bad offensive line can make a good team look bad.
Many times we have seen a team with a bad record bring in a high-profile offensive lineman the next offseason and proceed to post a winning record (for example, the Dolphins bringing in tackle Jake Long after their 1-15 season in 2008).
