This is from NFL.com by Gregg Easterbrook. We should pay attention: Why are the Pittsburgh and Seattle offensive lines so good? One reason is seven of the 10 were originally drafted by their teams. Four of five players on both offensive lines have been starting together for four years, meaning they know each other's moves. Offensive line moves are more important than spectators realize: think of Tobeck turning the wrong way. Teams seeking success ought to follow the Pittsburgh and Seattle offensive line model -- invest draft choices in blockers, then keep them together as a unit for an extended period.
