The situation: J.J. Watt receives a hero's welcome when he is introduced pregame. After his name is announced to a deafening roar, Watt sprints from the tunnel carrying the Texas flag and passionately waves it to get the crowd fired up. Watt has been the face of the Texans' efforts to aid with recovery from Hurricane Harvey. In the two weeks since Houston was hit with devastating flooding, Watt has helped raise more than $30 million for a Houston flood-relief fund.

"That was a good moment, but it was downhill from there ..." -- Texans defensive end J.J. Watt, on Houston's 29-7 loss to the Jacksonville Jaguars

The situation: Facing an emotional Houston crowd, the Jaguars get the ball first and begin the first drive of the game at their own 25-yard line.

The play: Jacksonville faces an amped-up NRG Stadium and Texans defense, and it shows on the first snap, when the Jaguars are whistled for a false start on tight end Marcedes Lewis. But they recover and move the ball before the drive stalls on the Houston 24-yard line. The Jaguars settle for a 42-yard field goal by Jason Myers.

"There were glimpses of some decent plays, but clearly it was a bad day." -- Texans head coach Bill O'Brien

The situation: Trailing 12-0, the Texans are on the move at the Jaguars' 37-yard line with a minute left to play before halftime.

The play: The Texans avoided disaster a few plays earlier when a replay challenge ruled that Houston quarterback Tom Savage's arm was moving forward when he was hit as he threw, wiping out a 45-yard fumble return for a touchdown by Telvin Smith. They didn't have the same luck this time, when Savage is stripped of the ball by Yannick Ngakoue and Dante Fowler Jr. scoops it up and races 53 yards for a touchdown and a 19-0 lead. In perhaps yet another sign of a return to normalcy -- at least for a few hours -- the Jaguars' celebration in the end zone is met with a chorus of boos by Texans fans.

"I thought Tom really hung in there and played tough." -- O'Brien, on Savage

The situation: Tom Savage completes 7-of-13 passes for 62 yards and loses a fumble that is returned for a 53-yard touchdown by the Jaguars and has the Texans in a 19-0 hole as the second half starts.

The play: Texans coach Bill O'Brien sees enough of Savage and turns the offense over to first-round pick Deshaun Watson, much to the delight of the Houston crowd. The Texans' offense gets the spark it needed. Watson completes his first NFL pass to DeAndre Hopkins for 8 yards and a first down. His mobility keeps plays alive and away from a Jacksonville pass rush that had six sacks in the first half and 10 on the day. He caps off an impressive 14-play, 75-yard drive with his first career touchdown pass -- to Hopkins -- for 4 yards. That cuts the Jaguars' lead to 19-7. Watson completes 5-of-8 passes for 37 yards and rushes for 9 yards on his first NFL drive.

"He [Bill O'Brien] said, 'Let's go. Let's go lead these boys, get a touchdown and try and turn the game around.'" -- Texans quarterback Deshaun Watson

The situation: The Texans trail 26-7 with 3:45 remaining in the game and are on a 45-yard drive down to the Jaguars' 20-yard line.

The play: After leading a touchdown on his first drive, Deshaun Watson looked more like a rookie on the next three drives. One second-and-goal, the QB is intercepted by Tashaun Gipson, who returns it 67 yards to tie up the Jaguars' surprising show of dominance in their season opener. Watson finishes the game 12-of-23 for 102 yards with a touchdown and an interception, setting up an interesting decision for O'Brien heading into a Thursday night matchup with the Cincinnati Bengals in Week 2.

"First career NFL game, so there's a lot to learn from. Watch the tape and then move on." -- Texans quarterback Watson
