In 2015, the Titans finished sixth in the NFL in sacks per play, and the running defense (8th in rush average) improved compared to the previous season. LeBeau liked what he saw most the season, but he didn't like all the big plays allowed. He also didn't like the fact the Titans allowed 30 points or more in the last five games.

Prior to joining the Titans, LeBeau served as defensive coordinator for the Steelers for 11 seasons (2004 – 2014). Overall, he's spent 13 seasons (1995-96, 2004-14) as defensive coordinator for the Steelers, during which time the defense finished in the top five in defensive rankings 10 times, and five seasons as number one in defense (2004, 07, 08, 11, 12).

"I want to get better in every single category,'' LeBeau said of the Titans. "When you take where we were after the 2014 season and see where we were after the 2015, you'd have to say we made significant progress. I want to continue with that progress, and that's in all areas. I don't want to get fat and happy with any of them. … I want to acknowledge they made solid progress, but we have to keep getting better."

On Thursday, LeBeau joked when asked about his secret to success, and why he continues to coach while others his age are enjoying retirement.

He'll turn 79 in the fall, but looks much younger.

Is it the exercise?

"I stay active. I am more of a walker,'' LeBeau said. "I love to play golf. If I ride, which I often do since I don't carry my clubs, I park the damn cart away from my golf ball and walk to it and walk back. I am always moving on the practice field. You have to have exercise."

How about the diet?

"I am on a see-food diet. I see food, and eat it,'' he said with a smile. "I just try and be smart. I try not to put too much poison in my body. Your body will tell you if you are overdoing anything, so I try and listen to my body."

More than anything, he just likes being around positive people.

And winning.

"I like Tennessee a lot. I really love being here,'' LeBeau said. "We just have to win more games and that will make it even better."
