ALLEN PARK -- Ricky Jean Francois still has never seen the house he had built this summer.

The veteran defensive tackle got the call from the Lions with a job offer, his sixth in 10 years, and bolted for Allen Park, leaving the new home to his wife and 2-year-old son until he could get back.

His chance to check it out is finally going to come this week. It's the Lions' bye, and he'll fly home Wednesday and eventually make his way to his theater room, where he'll have his iPad, his cell phone to text with other players and one objective in mind: to watch all the negative plays the defense has had this season.

Yes, the Lions are fresh off a 31-23 win over Aaron Rodgers and the Packers, but Francois has seen this before, the way complacency can settle in. He felt it was there after the upset of the Patriots, when Detroit came out and allowed 240 yards to Ezekiel Elliott alone in a road loss to the Cowboys.

Those issues didn't disappear with a win over the Packers. And Jean Francois wants to make sure they do disappear at some point so as not to make those two wins meaningless in the grand scheme of the season.

"We know what teams are going to game plan. We know what teams are going to do. They've seen us have gaps and holes in he run game and pass game," Francois said. "As long as I have it and I know what we can see and what we can improve at, that's the first step right there."

How many negative plays that will be, he isn't sure. A negative play doesn't necessarily carry a negative result, and a negative result isn't necessarily the result of a negative play. But Francois will trust Matt Patricia, the coach he followed over from New England, and the defensive assistants to find the right number. They know what they're looking for and when it doesn't look right.

It hasn't looked right a few times for the Lions defense this season. At 2-3, they've scored big wins over the Packers and Patriots but have been gashed on the ground in their three losses, with an average of 181 rushing yards a game and 5.5 rushing yards per carry allowed in those games. In wins, the numbers are better but still a concern, with 93.5 rushing yards per game and 4.8 yards per carry allowed.

Francois has consistently said that focus has been the issue for the Lions. He just doesn't notice it until the team is out on the field and experiencing the slogs in the games. He wants to see that get corrected and understands it won't be an immediate switch.

"I won't blame you to lose focus this week. This is the bye week. You can lose focus all you want this week," Francois said. "But right now, make sure you still peek at football. Just don't lose it all.

"If you want to make that playoff run, become a championship team, division championship, whatever it may be, the first thing you've gotta do is you've gotta become focused."
