The high temperature in San Diego on Tuesday is expected to be around 75 degrees, about the usual for this time of year. So to his teammates who think it's hot at the San Diego Chargers' training camp, offensive tackle D.J. Fluker has a different opinion.

"I went back home to Alabama (after minicamp), where it's very hot," Fluker said after a recent practice. "This heat isn't too bad. For some people, it's a little bit different."

Fluker was a prep standout at McGill-Toolen in Mobile and at Foley.

Fluker has kept his cool while some of his teammates haven't. Reporters gathered around Fluker asked about a fight between an offensive lineman and a defensive lineman at practice.

"That's what it's all about. It's competition," Fluker said. "You've got to learn how to take a whooping sometime. We're very competitive. You've got to compete to be out here. If you ain't a competitor, you need to go home. I love the intensity. That's what it's about. It's about being a grown man. ... Sometimes you're going to have fights."

While Fluker is accustomed to the heat, he's also more comfortable at training camp this year. The Chargers selected Fluker out of Alabama with the 11th choice in the 2013 NFL Draft and installed him as the starter at right offensive tackle almost immediately.
