This offseason in the NFL there were a dozen changes at offensive coordinator. That’s just over one-third of the league making a change on a vital part of its coaching staff.

So what can we expect from not only those 12 teams but the other 20 clubs as well when it comes to moving the football, finding the end zone and putting points on the board in 2014?

The search is over.

With the regular season kicking off in three weeks, we are taking time to power rank the NFL’s 32 offensive units.

Remember, these rankings don’t necessarily reflect point totals of the upcoming season. There’s certainly more than one way to light up the scoreboard in the NFL.

For instance, when it comes to the passing attack, we have seen record numbers the last two seasons when it comes to interception returns for touchdowns. And let’s not forget the impact special teams have on the game. For instance, it’s worth noting that in each of the last two Super Bowls, the eventual winning team returned the opening second-half kickoff for a score.

Each team’s offseason arrivals and departures, the impact of the 2014 draft class, and factors such as red-zone efficiency, sacks allowed, turnovers and yards gained all add up to us forecasting the worst to the best when it comes to NFL offenses in 2014.
