Nick Chubb and Georgia’s host of running backs will have help this season.

The Bulldogs’ impressive backfield will attack defenses from behind one of the SEC’s top offensive lines, a unit returning four starters led by veteran bookend tackles and multi-year impact players John Theus and Kolton Houston.

Anchored by center David Andrews last fall, Georgia averaged an SEC-best 257.9 yards per ground on the ground with 38 total touchdowns thanks to Todd Gurley and the emergence of true freshman Chubb midway through the season.

The Bulldogs could exceed those numbers in 2015 with immense backfield depth if they find a serviceable replacement in the middle for Andrews, a player with 50 career starts.

Thus far this spring, Hunter Long and Isaiah Wynn have battled head-to-head for the position while Georgia’s wall of blockers adjust to first-year assistant Rob Sale’s blocking styles. Sale replaced Will Friend on staff as the Bulldogs’ offensive line coach after Friend joined forces with former Georgia offensive coordinator Mike Bobo at Colorado State.

The coaching switch shouldn’t alter Georgia’s focus on the run, its primary strength as a likely preseason division favorite with as much experience and depth it has had up front in several years.

Most would agree that the continued progression of juniors Greg Pyke and Brandon Kublanow, projected to start at right and left guard respectively, are two of the most important pieces.

Pyke is a massive 6-foot-6, 320 pounds and an ideal short-yardage option to run behind while Kublanow became a force and started every game inside last fall after winning the job during preseason practice.

Keeping quarterback Brice Ramsey upright and protected in the pocket shouldn’t be an issue if this unit remains healthy. The Bulldogs gave up just 17 sacks a season ago, one behind Florida for second-fewest in the Eastern Division.

Georgia’s had extreme success in play-action situations in recent seasons and that plays into Ramsey’s strengths as a kid with presence and a big arm.
