"The last 10 years I've been coaching in the South I really do believe there is a cumulative effect over the course of the season, from August until the end of the year, when you're out here, even if it's for walkthrough at 12, 1, 2 (p.m.) and it's 95 degrees and the sun is beating on you," Koetter said. "I just think there's a cumulative effect. We are going to do everything we can to try to chip away at that. There's some things we can't get away from, but we're going to do what we can."
