Seven wins in a row is nice.

But the Texans want more. A lot more.

"We haven't done a thing," Bill O'Brien said Monday afternoon.

The head coach wasn't throwing cold water on the team's win streak. Instead, he was pointing out Houston was after bigger things. O'Brien's also mindful of the next opponent: a Titans squad that upended the Texans in Week 2.

"We've got a very, very difficult opponent coming in here on Monday night that beat us earlier in the season," O'Brien said. "We've got to get back to work because in the end, what have you done? It's better to be able to say that after a win, obviously, but we've got to really work hard to get better every week."

Safety Tyrann Mathieu, who tallied a sack and nine tackles in Sunday's 23-21 win at Washington, described the team's mindset on Monday back in Houston.

"Just trying to take control, obviously, finishing the season strong," Mathieu said. "Doing our jobs each and every play, and then playing with attitude and great effort."

At 7-3 and atop the AFC South, the Texans welcome a Tennessee squad that's 5-5 and coming off a 38-10 thrashing in Indianapolis. Despite those struggles, O'Brien said the Titans will be a challenge at NRG Stadium next Monday night.

"They just had a little bit of an off day yesterday but they're a very good team," O'Brien said. "They just beat the Patriots two weeks ago, in Tennessee, 34-10.

Aside from the wins at Jacksonville and at home over the Dolphins, every other contest this season has been decided by a touchdown or less. Houston's been on the winning side in five of those eight one-score games, and linebacker Brennan Scarlett described how the Texans have mentally handled those close situations.

"We've been in this position before," Scarlett said. "We've had a lot of close games. I think this team's gotten to the point where, through everything, we believe that we're going to win. You can feel that on the sideline. You can feel that confidence."

Quarterback Deshaun Watson agreed.

"The ball has just been going our way and we just kept believing and kept fighting," Watson said. "We knew that if we listen to the locker room and no one else, no outside noise, that we'll be just fine."

Watson and company are off Tuesday, and will resume practice on Wednesday.
