Things are rather cyclical in the NFL, at least in the last decade or so.
During that time, things like the importance of offensive lines, an emphasis on the running game, and the usage of fullbacks and nose tackles seemingly disappeared as teams gravitated more towards the run-and-gun style of offense that has become rather popular in the game today — at all levels.
However, things are starting to swing back towards the old-school style of football, placing a greater emphasis on the play in the trenches on both sides of the football.
That is especially true for the Pittsburgh Steelers, who have rebuilt the offensive line and are aiming to play bully ball moving forward under head coach Mike Tomlin.
