2013 NFL Offensive Line Rankings

Added: Adam Snyder (G)

Lost: Leonard Davis (G)

Drafted: Carter Bykowski (T)

Backups: (T): Kenny Wiggins, Al Netter, Carter Bykowski, Luke Marquardt (G): Joe Looney, Adam Snyder, Wayne Tribue, Patrick Omameh (C): Daniel Kilgore, Sherman Carter

Season-ending Rank: 4

Fantasy Outlook: The Niners' line ended last season as the fourth-best group in these ranks thanks in large part to uninspiring sacks allowed totals. The majority of their problems came in just a few games though, and the conservative approach of former quarterback Alex Smith played a hand in those numbers too. This group is monstrous, athletic, and have been together for a good stretch of time now. Each of their five starters ranked within the top-10 at their position according to ProFootballFocus.com. Without a true weakness and an elite left tackle to anchor the group, San Francisco's line gets first crack at the top spot. Few teams can push around defenses up front and dominate contests on the ground like the Niners can.

Added: Louis Vasquez (G)

Lost: Dan Koppen (C)

Drafted: Vinston Painter (T)

Backups: (T): Chris Clark, Vinston Painter, Paul Cornick (G): Manny Ramirez, Chris Kuper, Manese Foketi (C): Philip Blake, C.J. Davis, Quinton Saulsberry, Justin Boren

Season-ending Rank: 1

Fantasy Outlook: The Broncos finished the season atop these rankings and debut at the number two spot for 2013. They lost veteran center Dan Koppen who worked well with Peyton Manning in their one season together. How J.D. Walton handles the responsibilities of the position will be the key to this unit moving forward. Louis Vasquez was signed via free agency to play right guard. He's a solid player and his presence gives this group a lot of depth as Chris Kuper is currently slated as a backup. He's had trouble staying healthy the past couple years but would start on most teams. Ryan Clady was hit with the franchise tag and he and Orlando Franklin form a nice tandem at the tackle spots. This isn't the biggest or most powerful line in the NFL, but they fit what this offense wants to do very well and showed great cohesion a year ago.
