AUBURN, Ala. - Clint Moseley is a small-town guy about to arrive in college football’s bigtime. The sophomore quarterback for No. 19 Auburn will make his first career start Saturday for the 19th-ranked Tigers at No. 1 LSU, a daunting debut that he’s embracing.

“It couldn’t get any better,” Moseley said Tuesday. “Aggressive defense. No. 1 team in the country. All the hype coming up to it. It’s Death Valley. Yeah, it’s a little nerve-racking, but at the same time how could you draw it up better?

“That’s just the most dramatic situation you can think of. That’s just awesome.”

If Moseley does indeed start, it will mark the third straight week that LSU’s opponent has gone with a backup quarterback.

Florida started freshman Jacoby Brissett against LSU on Oct. 8 after senior starter John Brantley and freshman backup Jeff Driskell were both sidelined by ankle injuries.

Saturday at Tennessee, the Volunteers started senior Matt Simms a week after starter Tyler Bray suffered a broken thumb on his throwing hand.

Auburn’s Moseley is replacing Barrett Trotter, who started the first seven games but completed only eight passes in the past six quarters for the nation’s 106th-rated pass offense.

The 6-foot-3, 223-pounder from tiny Leroy, Ala., has attempted nine career passes, and all four completions came in the second half of Saturday’s 17-6 win over Florida.

Trotter and Moseley battled to replace Cam Newton through spring practice and into preseason camp. When Trotter won out, Moseley called it “the disappointment of my life.”

Challenge No. 1 as starter: Take on a playmaking LSU defense that ranks fourth nationally in total defense. And do it possibly without Auburn’s injured two top receivers, Emory Blake and Trovon Reed, who Chizik said are “50-50” for the game.
