Three weeks ago, the Texans were sitting at 0-3 at the bottom of their division. Three weeks and three consecutive wins later, the AFC South has flipped. Houston regained its momentum following Sunday's 20-13 win over the Buffalo Bills and after back-to-back overtime wins against Indianapolis and Dallas.

"I feel good," head coach Bill O'Brien said Sunday. "I feel good for the guys in there. I think that was a really important win right there. But, I also know that we're not going to be able to be where we want to be unless we figure this thing out on offense. And, figure out what we have to do to be able to run the ball, throw the ball consistently, and at times we look like a good offense, not really today, but at times we have this season. We have to figure that out. But, as a team this is a very, very tough, competitive, resilient football team that will do anything to win and that's what I'm most proud of relative to coaching these guys."

Defense and special teams stepped up and made momentum-shifting plays. Brennan Scarlett recovered a muffed punt and then a punt return blocked by Tyrell Adams in the first half. The Texans converted the turnovers into 10 points. Watson connected with DeAndre Hopkins for a touchdown after the early muffed punt recovery. Watson, limited in practice last week with a chest injury, completed 15-of-25 passes for 177 yards, one touchdown and two interceptions in the win.

"It was alright," Watson said of his injury. "I don't want to make any excuses on that with the injury. But, the game had some ups and downs. It started off fast, and then we got in a little slump. Then the last drive was very key to try to get points on the board. But overall, it was fine."

When Watson and the offense struggled to score late in the game, the Texans defense stepped up and delivered the points. Late in the fourth quarter, when Houston was tied 13-13 with Buffalo, Johnathan Joseph picked off Bills quarterback Nathan Peterman and scored on a 28-yard touchdown return. The Texans regained the lead with 1:23 remaining.

"Yeah, it was an incredible play," J.J. Watt said. "I mean, obviously a gigantic play in the game. Really didn't want to play another overtime, so very glad he was able to do that. I mean J-Jo. (Johnathan Joseph) is a vet, savvy, been around the league a long time. Huge play when we needed it."

The Bills next and final drive of the game ended in another interception, this one by Kareem Jackson. The Texans defense held the Bills to 229 total net yards (100 rushing and 129 passing) and 12 first downs (four rushing, eight passing).

"These type of games are when you deal with adversity and end up coming through, brings you together as a team," Scarlett said. "Down in the long run, these type of games are really going to benefit us. We've come together as a team and we'll keep it rolling."

In Week 6, the Titans fell 21-0 to the Baltimore Ravens, the Jaguars lost 40-7 to the Cowboys and the Indianapolis Colts fell 42-34 to the Jets. For two consecutive weeks, the Texans have been the only AFC South team to win. On Sunday, Houston will travel to Jacksonville for a chance to regain the No. 1 spot in the division.

"We're back where we want to be," Watson said. "We've got a great opportunity next week on the road in Jacksonville. The season is still in front of us. We just kept believing, we're going to keep believing, keep pushing forward and keep fighting. This is a special team for what we've been through these past six weeks. I love all of the guys in the locker room. The locker room is very special. No one flinches, and everyone just keeps fighting and trying to finish the game out. And that's what we've been doing. We're just going to keep building on this win and keep trying to improve."
