Since the NFL is a copycat league, the teams that dream up something exotic, shift a few key pieces or mix up a coaching staff often climb the offensive rankings fastest.

Such changes are a part of the reason the offensive hierarchy looks so different every year—only teams with a Tom Brady or someone close are immune to the shuffle.

Look at last season. The Los Angeles Rams seemed dead in the water entering the year, yet adding left tackle Andrew Whitworth and new head coach Sean McVay resulted in a top-10 offense in yards per game and 29.9 points per contest.

The team that lost Whitworth in free agency and stuck with the same coaching approach, the Cincinnati Bengals, went from a respectable top-13 offense in 2016 to last in yards per game and averaging 18.1 points.

With the 2018 NFL draft done, let's rank all 32 offenses based on last year's results and leaguewide additions in the coaching, free-agency and draft realms.
