The second-longest winning streak in the NFL? That would belong to the Houston Texans. The New Orleans Saints have won 10 in a row, and the Texans are right behind them at eight straight. Three games into the season, it seemed more likely that Bill O’Brien would be fired by now than the Texans having won eight in a row to take control of the AFC South. But after shaking off a slow start against the Tennessee Titans to cruise to a 34-17 win on Monday night, the Texans are 8-3 and have a two-game lead in the AFC South.
