HOUSTON -- There came a testy moment early in the season when Houston Texans coach Bill O'Brien declared he didn't care one bit about the percentage chance of a team that started as poorly as the Texans did making the playoffs.

It was slim.

Since 1990, about 11 percent of teams that started 0-2 had made the playoffs. Only six teams that started 1-4 -- as the Texans did -- made the postseason.

O'Brien's instinct to ignore all that was right. Here the Texans are, on the verge of making the playoffs, having won in Indianapolis for the first time in franchise history. They can leave no doubt by winning their next two games, and even if they don't win both, there's a good chance they'll be a postseason team. If they are, they might have to reverse a historical trend again.

According to ESPN Stats and Info, no team has ever won a playoff game during a season in which it had four different quarterbacks start. There's a decent chance the Texans will have that happen with Brian Hoyer still going through the concussion protocol. Hoyer has practiced the past two days, but he has not been cleared to play yet.

If Hoyer can't play, Brandon Weeden will start for Houston on Sunday against the Tennessee Titans. The Texans have also had Hoyer, Ryan Mallett and T.J. Yates start for them this season.

In the past 30 seasons, only five teams have made the playoffs after having four different quarterbacks start. According to the Elias Sports Bureau, those five teams were the Packers in 2013, the Broncos in 2003, the Browns in 1988, the Bears in 1987 and the Bears in 1986.

None of those teams won a postseason game, which is something the Texans would hope to do if they make the playoffs.

Just because it hasn't happened yet doesn't mean it can't happen. This year's Texans have made a habit out of bucking historical trends.
