GAINESVILLE, Fla. -- Every time a new quarterback plays, there are wrinkles that show up. Both for the opposing team and the offensive coordinator who now has to get used to his new signal-caller.

On the road at Tennessee when Purdue graduate transfer Austin Appleby took over, some of the unexpected showed up in the second half as the Volunteers got back into the game. With Tennessee competitive again, the fans cranked it up to another notch. Appleby didn't respond well, admitting afterward that he let the noise affect him.

Jim McElwain's message ever since has been pretty basic.

"Coach Mac every single day goes, ‘Hey guys ... ’ and we all say it after him like it’s an elementary school ‘Communicate, communicate, communicate,’" Appleby said. "We do it over and over and over again. And it’s for real. When it’s loud and you can’t hear yourself think, it’s our job to communicate the calls from the center all the way out."

Appleby started a game at Vanderbilt following the Tennessee outing, but nearly half the fans were Florida fans. That experience won't hold a candle to this week at LSU.

For the first time since that second-half debacle against Tennessee, Appleby will face an incredibly hostile road environment.

"We’re going to have a test on our hands with the crowd noise, obviously, and it’s nothing we can’t overcome," Appleby said.

McElwain was pretty blunt when asked about the struggles at Tennessee on Monday.

"Well they shouldn’t have been issues anyway," the second-year coach said. "To me they were excuses.

"Don’t let it happen again. That’s what you take away from it."
