If you want a clear delineation between wins and losses for the Houston Texans, you can find it in red-zone efficiency.
In the Texans' first two games, their only two wins this season, their offense entered the red zone seven times and scored touchdowns every single time. Since then the Texans have scored touchdowns on only 2 of 12 red-zone trips.
John McTigue of ESPN Stats & Information looked into the breakdown of the plays for me.
He found that of the 53 red-zone plays the Texans have run, 28 have been passes and 25 have been runs. Only 10 of those passes have been thrown into the end zone. That means 35.7 percent of the Texans' red-zone pass attempts have been thrown into the end zone, ranking them 19th in the NFL. Only 18.9 percent of the Texans' red-zone plays overall have been passes into the end zone, ranking them 17th in the NFL.
Here's what happened each week:
In Baltimore, the Texans' first red-zone trip began with an illegal-substitution penalty on the Ravens that converted a fourth-and-4 and took the Texans to the Ravens' 18-yard line. Then came a 10-yard Arian Foster run, followed by a run for negative yardage and two incomplete passes. Their next red-zone trip also was aided by a Baltimore penalty. Once inside came a 4-yard run, a 3-yard run and then a pass for negative yardage before the field goal.
Against the Seahawks, the Texans' first red-zone trip ended in a Matt Schaub interception. Their second resulted in a touchdown and their third a field goal. That field goal came on a drive that began at Seattle's 19-yard line. Schaub threw four passes and completed one of them. Foster ran twice for a total of 7 yards.
The one and only red-zone trip against the 49ers ended in a missed 45-yard field goal. The drive had stalled because of a holding penalty on Owen Daniels. That knocked the Texans to a third-and-11. Then Daniels false-started, and the ensuing third-and-16 was too much for Houston to overcome.
Of the Texans' six red-zone trips against the Rams, four came when the Texans were already down by 25. Two ended in T.J. Yates interceptions, one ended in a touchdown and the last ended with the end of the game. The Texans' two first-half red-zone trips ended in field goals. The first stalled with a third-down false-start penalty on right tackle Derek Newton, then a 7-yard pass on third-and-9.
Getting there is the first challenge, but the lack of red-zone productivity explains why the Texans' offensive yards per game ranks seventh in the league, but their points per game rank 26th.
