Signing Steven Jackson gives the Atlanta Falcons the best offense in the NFL. The Falcons have agreed the signing of the star free agent running back, according to

Jackson expands the repertoire and scoring potential of the Falcons attack. He will provide the perfect complement to the league's most dangerous passing game.

Quarterback Matt Ryan already has the perfect blend of pass-catchers. At wide receiver, Julio Jones stretches the field vertically, while Roddy White works the outside.

Veteran tight end Tony Gonzalez, who recently confirmed he will 'return' for another season, works underneath. The only element missing is a dynamic and versatile weapon in the backfield.

Jackson is exactly that. The stellar veteran offers the same level of bruising, power-running that the departed Michael Turner did.

However, unlike Turner, Jackson is more than just dominant between the tackles. Even at 29, he still possesses exceptional footwork and coordination.

He boasts an array of quick moves, including a powerful jump cut. Jackson will offer more big play potential on the ground than Turner could muster.

More importantly, he is a greater threat as a receiver. Jackson has registered over 300 yards receiving in all but two of his nine pro seasons.

That's something Turner never offered. In five seasons in Atlanta, he recorded a mere 60 receptions.

With Jackson added to the mix, the Falcons now have too many weapons for defenses to cover. Jackson's skills as a runner will also provide true balance alongside Ryan's aerial attack.

Defenses facing the Falcons now have a nightmare dilemma. Do they bring safeties up to the line to stop the man who has recorded eight-straight 1,000-yard rushing seasons?

If they do, Ryan and his versatile set of receivers will terrorize undermanned coverage schemes. If a defense sits back in nickel and plays pass-first, Jackson will dominate on the ground.

By signing Jackson the Falcons have acquired the missing piece that makes their offense the best in the NFL and the franchise major contenders in 2013.
