Recently, Sam Monson and the Pro Football Focus analysis team ranked all 32 teams in the NFL by their current roster. Now, we take a look at all 32 teams in further depth. Below, you'll see not only where each team's offense ranks, but also how each position group -- quarterbacks, running backs, offensive line and receivers -- grades out against the rest of the NFL.

In order to compile the ranks, we used PFF's graded depth charts series as a starting point to grade and rank position groups throughout the league. Then, we weighted those rankings toward starters and moderated our expectations for rookies, according to the performance PFF data expects them to achieve in Year 1 by draft position.

The color-coded images at the right of every team include the team's NFL ranking in each of the four position groups. Offenses are divided into four position groups: quarterbacks, running backs (including blocking backs), receivers (wideouts and tight ends) and the offensive line.

With our third-ranked quarterback situation, and plenty of talented targets for Drew Brees to throw to, it's easy to see why the Saints are our highest-ranked offense heading into the 2014 season. There's not much Brees struggles with as a passer, and he finished last year with the most touchdown passes (15) and second most yards (1,128) in the league on passes thrown 20 yards or farther downfield.

Of course it helps to have the weapons around him, with Jimmy Graham the standout among the tight ends and receivers. Graham's 2.26 yards per route run average was the most of any tight end with enough qualifying snaps last year, and figures to be just as dangerous in 2014.
