Our list of the SEC’s best and worst Week 3:

STUDS

1. Leonard Fournette: LSU’s sophomore running back is on a tear dating back to the end of last season, and he turned in his best performance yet Saturday against Auburn. Rushing 19 times for 228 yards and three touchdowns in less than three full quarters of work, Fournette jumpstarted his Heisman Trophy campaign in earnest with a pair of runs in which he left a trail of would-be tacklers in his wake.

2. Greyson Lambert: Lambert was as close to perfect as any NCAA quarterback has ever been from an accuracy standpoint Saturday, setting the national record for completion percentage by hitting of 24 of his 25 pass attempts. He accounted for 330 yards and three touchdowns through the air, and led the Bulldogs to their highest point total against South Carolina since 1974.

3. Trent Sherfield: Sure, it was against Austin Peay, but when you pull in 16 catches for 240 yards like Vanderbilt’s sophomore wide receiver did on Saturday, you’ve earned a mention here. The Commodores got their first win of the season, thanks largely to Sherfield’s performance, which broke Earl Bennett’s school record for receiving yards in a single game.

DUDS

1. Alabama’s ball security: It’s difficult to overcome a five-turnover deficit. Ole Miss deserves credit for going into Tuscaloosa and taking the Rebels’ second straight win against Alabama for the first time in series history. But in a game in which the Tide outgained Ole Miss by 70 yards, dominated time of possession, and had nearly twice as many first downs, the turnovers were the obvious cause of Alabama’s downfall. Crimson Tide quarterbacks threw three interceptions and Alabama fumbled twice on kickoff returns in the first half.

2. Auburn rush defense: The Tigers were physically dominated in the run game Saturday, and it wasn’t all Fournette’s feats of super-human ability. Auburn gave up more than 400 yards on the ground and 8.6 yards per carry as the LSU pushed the Tigers around up front. Auburn should improve when Carl Lawson returns, but the problems exposed in the last two weeks are more than one player can reasonably be expected to fix.

3. Arkansas’ second half: The Hogs went into halftime tied, 21-21, and matching Texas Tech blow for blow. But in the final two quarters Arkansas fans were forced to witness a Toledo redux. The Razorbacks defense couldn’t get Texas Tech off the field when it needed to, and Arkansas’ only three second-half possessions yielded just a field goal, a missed field goal and a fumble.
