Possibly, if they do their part in Detroit today.
The Texans secure a playoff spot if:
1. Houston win + Tennessee loss or tie + Miami loss or tie + New York Jets loss or tie + Cincinnati loss + San Diego loss or tie.
2. Houston win + Tennessee loss or tie + Miami loss or tie + New York Jets loss or tie + Cincinnati loss or tie + Pittsburgh loss.
After suffering through those early seasons of futility here in Houston and watching a beat up team win their first ever playoff game last season, it is great to see them dominating. And I've seen the figure bandied around that they are 99.8% likely to make the playoffs, so I'm looking forward to a second year of post-season play!
