It's definitely taken a step down since the spike in pass-friendly rules, but I think the importance of a RB is still great. If you look at the dominant teams in the league, they all have solid running games. The Seahawks, Packers, and even Patriots had respectable running games. And I consider those to be the top three teams last season. When you take a look at teams who have good regular seasons, followed by disappointing post seasons, they typically struggle on the ground. For example the Broncos. Even the Packers couldn't get it done in 2011 when they went 15-1 in the regular season. They failed to run the ball in the playoffs and got beaten by the less talented Giants. I agree passing is the main focus in offenses these days, but a running game puts teams over the top. I used to be on the bandwagon of RBs being phased out until Green Bay drafted Eddie Lacy. He vastly improved our offense and the way we can play games.
