"I've had a lot of people tell me every year they are going to get me (an iPhone) for Christmas," Klug said with a smile. "I politely tell them I would decline it or I would return it. I appreciate the offer, but I don't want one. I'll stick with the flip phone."

So what's his hang up?

"My idea there is if you have your phone in your hand and are always looking at it, it's like me carrying around an iPad all day, and I don't want that," Klug said. "I just don't want to have the temptation of having the Internet right there with you. I don't want it to be a distraction."

Klug's teammates are dialed into his choice of technology, and can hardly believe it.

On Thursday, in fact, one coach made a comment to Klug as they walked the hallways of Saint Thomas Sports Park. Klug had just put his black flip phone back into the pocket of his sweatpants.

"I retired the flip phone when I was in high school," Titans safety Kevin Byard with a smile. "I could probably still text on the flip phone, 2233, stuff like that. I think I could make it work, but if I don't have to, I won't do it."

Titans defensive tackle Antwaun Woods was asked if he knows of any other NFL player who still uses a flip phone.

"I don't know anybody in my life in 2017 who has a flip phone," Woods said laughing. "The last time I had a flip phone was probably in 2006."
