Here’s our weekly look at the SEC quarterbacks with most difficult assignments on Saturday.

Greyson Lambert, Georgia

Opponent: No. 13 Alabama

Somewhere in the second half of the Vanderbilt game, Lambert turned a corner. Or so it seems.

After missing his first seven passes against the Commodores, the transfer from Virginia has been virtually flawless in providing some needed balance to the Georgia offense. Through the last two and a half games, he’s completed 44 of his last 49 passes for 592 yards with five touchdowns and no interceptions.

Regardless of the defenses the Bulldogs have faced, those numbers are pretty spectacular. Nonetheless, Alabama presents a challenge unmatched by Georgia’s opponents this year. For the second consecutive year, the Tide are giving up yards through the air, but there’s actually been improvement against the pass this season. While Alabama ranks 11th in the SEC in passing yards allowed, it’s third in the conference in terms of pass defense efficiency. The Tide is also effective at disrupting opposing quarterbacks, posting 11 sacks through four games.

Perhaps equally important, Alabama matches Georgia’s strength with its own. The Bulldogs have one of the conference’s best running games, while the Tide leads the SEC and ranks fourth in the nation in rushing yards allowed per game (56.8) and is third in the nation in yards allowed per carry (2.0).

It seems doubtful that Alabama will completely shut down Nick Chubb, but it’s equally unlikely that Georgia can win Saturday without Lambert making his share of plays.

Chad Kelly, Ole Miss

Opponent: at No. 25 Florida

Two weeks ago Kelly and Rebels walked into one the SEC’s most inhospitable environments against one of the nation’s best defenses and left with a win. Now they get the pleasure of trying to do it again.

The Swamp should be rocking Saturday with the Gators riding high after last week’s stirring comeback against Tennessee moved them to 4-0. Along with the crowd, the Florida defense — which ranks among the SEC leaders in passing defense, total defense and sacks — promises to make life less than 100 percent comfortable for Kelly.

The Rebels passed their first major test, putting up more than 40 points with Kelly passing for 341 yards and three touchdowns on a talented Alabama defense in Tuscaloosa. That win lifted Ole Miss into the national playoff discussion. To stay there, Kelly and the Rebels will need to repeat the feat.

Drew Lock, Missouri

Opponent: vs. South Carolina

The Gamecocks aren’t the world’s toughest matchup — South Carolina enters Saturday ranked 12th in the SEC in passing yards allowed. It’s everything else that surrounds this week’s game that makes it a tough assignment for Lock.

First, the obvious: Lock is a true freshman making his first career start due to the suspension of Maty Mauk. Gary Pinkel and the Missouri coaching staff has worked Lock into games this season, but Saturday will represent his first extended action. He’s performed reasonably well to this point and shown good arm strength, completing 15 of 25 passes for 225 yards with one touchdown and one interception. But there will be another level of pressure heaped on the young quarterback this weekend.

The Tigers, two-time defending champs of the East, are coming off a loss to Kentucky in which their sputtering offense finally cost them. Missouri has struggled to run effectively behind a retooled offensive line and with Russell Hansbrough still bothered by an ankle injury. If the Tigers hope to avoid their first back-to-back losses since 2012, they’ll need Lock to provide a spark to an offense that currently ranks last in the SEC in scoring and yards per game.
