O-line rankings:who is better?

 New Orleans Saints: There were only two teams that ranked in the top 10 of both run and pass-blocking efficiency last year according to Football Outsiders. It should be no surprise that those teams rank in the top two spots. Then again, it's a delicate situation. The Saints jerseyswere clearly the best unit in the league last year, led by guard Jahri Evans(notes),  who many people believe has surpassed Minnesota's Steve Hutchinson(notes)  as the best interior offensive linemen in the NFL. But the real key is that this group works very well together and is consistent at creating space for Drew Brees to step up or keeping defensive linemen from getting in his face quickly (Brees is susceptible to batted passes because he's only 6-feet tall). The running game is still something of a mirage, but this group makes it work.

New England Patriots: Critics will immediately say the Patriots are over-ranked at this spot. There's no debating that the group's high ranking is partially a reflection of the rest of the league being downright mediocre. The Pats have problems right now at left tackle, where Matt Light(notes) is close to the end. If they don't re-sign guard Logan Mankins(notes), the best of the group but who is so unhappy that he has demanded a trade, this unit is going into serious freefall. That said, few groups in the NFL work together as well as the Patriots jerseys. Obviously quarterback Tom Brady(notes), the fourth-most hit passer in the league, helps a lot. But it's still a good unit.

Baltimore Ravens: At a time when pass protection is so critical, the Ravens were below average last season with an adjusted ranking of 19 overall. That said, between having a young quarterback (Joe Flacco(notes) was in his second season), a couple of big changes on the line (guard Jason Brown(notes) left and rookie right tackle Michael Oher(notes) came in) and a lack of great weapons at the receiver spot (Anquan Boldin(notes) and Donte Stallworth were brought in this offseason), there is reason to believe improvement will be made. Oher is switching to left tackle, where he may quickly surpass Denver's Ryan Clady(notes) and Miami's Jake Long as the best at that spot.

 Atlanta Falcons: new Falcons jerseys linemen like to joke about their lack of talent. Really, it's a rallying cry for them to work together. While it's true that this group doesn't have overwhelming talent, it works together in much the same way that New England's unit thrives. If left tackle Sam Baker(notes) and third-round guard Mike Johnson(notes) progress, the Falcons will solidify this spot.
