Key stats in Georgia-South Carolina: Orth's passing, Chubb's inside run

Steve Spurrier has dominated Georgia throughout his career -- his South Carolina teams have won four of the teams' last five meetings and his 16 career wins against the Bulldogs is the most by any coach -- but he'll have his work cut out Saturday.

ESPN's Football Power Index gives No. 7 Georgia (2-0, 1-0 SEC) a 90 percent chance to win the game and most oddsmakers favor the Bulldogs to beat the Gamecocks (1-1, 0-1) by at least 16 points in Saturday's meeting at Sanford Stadium.

With an assist from ESPN's Stats & Information group, let's take a look at three key stats entering Saturday's game.

1. Orth making his first start: Former walk-on quarterback Perry Orth will make his first career start for South Carolina. These are not ideal circumstances for a player to make his starting debut -- Georgia has won 83 percent of its home games since Mark Richt became head coach in 2001 -- but Orth performed well after replacing an injured Connor Mitch last week against Kentucky.

Orth was particularly effective throwing downfield, completing 5 of 7 passes that covered at least 15 yards for a total of 118 yards, one touchdown and one interception. His Total Quarterback Rating on throws of 15-plus was a solid 89.4 compared to 11.8 for Mitch, was was 2-for-9 for 46 yards on such passes.

Without question, however, Georgia defensive coordinator Jeremy Pruitt will try to pressure Orth into mistakes. The Bulldogs are tied for the SEC lead in interceptions with South Carolina and Ole Miss (four) and they have a plus-three turnover margin. Georgia was plus-16 in turnover margin last season, Pruitt's first in Athens, which tied for fourth nationally.

2. Stopping Chubb: South Carolina defensive coordinator Jon Hoke will attempt something that every opponent has failed to do over the last 10 games: slow down Georgia running back Nick Chubb.

Chubb has rushed for at least 100 yards in each of the last 10 games, which is the second-longest streak in the FBS behind Toledo's Kareem Hunt (11). The Bulldogs sophomore is closing in on Herschel Walker's school record for consecutive 100-yard games (12), which he set between 1981 and 1982.

Georgia is averaging 259 rushing yards per game since the start of last season, 14 yards more than the next-closest SEC team. In that same stretch, South Carolina's defense has allowed 5.4 yards per carry, worst in the conference and 117th among all FBS defenses.

Runs between the tackles have been particularly damaging for the Gamecocks. They have allowed 6.2 ypc on inside runs this season, fifth worst among Power 5 defenses. Since becoming a starter last fall, Chubb is averaging 107 ypg on runs between the tackles, the most among active Power 5 players.

Even with an injured ankle, Chubb still ran for 189 yards on 19 carries last week against Vanderbilt. Keep an eye on how well Chubb moves on the sore ankle against South Carolina. Richt said he should be fine, but it still bears watching.

3. Georgia's passing problems: It's a good thing for Georgia that Chubb, Sony Michel and Keith Marshall have packed a powerful punch with the running game because the Bulldogs' quarterback play hasn't struck fear into opposing defenders' hearts.

Starter Greyson Lambert did not complete a pass in the first half against Vanderbilt last week (0-for-5), but managed to finish the game 11-for-21 for 116 yards. Nonetheless, Georgia's offense rarely moved the ball with anything approaching consistency against the Commodores.

Lambert's QBR through two games (67.6) ranks 49th nationally and is slightly better than that of backup Brice Ramsey (62.9) in limited work. The two have combined to complete 59 percent of their passes (23-for-39) for 333 yards and three touchdowns.

Bulldogs leading pass-catcher Malcolm Mitchell has just seven catches for 88 yards thus far. They have actually been most effective funneling the ball to running back Michel (four catches for 109 yards). Keep an eye on South Carolina linebacker Skai Moore in pass coverage. He has already picked off three passes -- two of which came in the end zone in the Gamecocks' season-opening win over North Carolina -- which ties for the FBS lead.

South Carolina's defense has not been particularly effective at shutting down the run and forcing opponents to pass, but the Gamecocks allowed Kentucky to gain just 92 yards in the second half last week after falling behind 24-7 at halftime. If they figure out a way to put the clamps on Georgia's running game, things could get interesting in Athens.
