FRISCO, Texas — Jason Witten had to figure the questions were coming after the Dallas Cowboys wrapped up the NFC East and home-field advantage in the playoffs with two games remaining.

The last time Dallas had the top seed secured before the end of the regular season, Witten was a fifth-year tight end in 2007. The Cowboys promptly lost their first playoff game to the New York Giants and watched their division rival upset undefeated New England in the Super Bowl.

So now the question is how the Cowboys (12-2) keep their edge with two games that won’t change their spot in the playoff bracket — starting Monday night at home against Detroit (9-5) — along with a bye before their postseason opener. The Lions are trying to secure a playoff berth.

“I don’t think it’s entered anybody’s minds,” Witten said Friday, a day after the Cowboys clinched thanks to the Giants’ 24-19 loss to Philadelphia . “I think we’re all aware of where it’s at. It’s a long time away, to think that you would rest or anything like that. Our job is to go play and coaches will handle those situations.”

For instance, will backup Tony Romo — the architect of that 13-3 season nine years ago — get playing time so that Dallas can protect Dak Prescott, the rookie who took the 10-year starter’s job with an 11-game winning streak?

What about left tackle Tyron Smith and defensive end DeMarcus Lawrence with their bad backs? Should Darren McFadden, last year’s leading rusher for Dallas, get more carries in relief of rookie NFL rushing leader Ezekiel Elliott because the nine-year veteran just returned from an offseason elbow injury?

Sorry. Coach Jason Garrett isn’t interested in discussing such things .

“We don’t really think about that,” Garrett said. “We’re focused on practicing and playing as well as we can in this game on Monday night against Detroit.”
