Today's game is the biggest for a Houston-based professional football team since the Oilers entertained Joe Montana and the Kansas City Chiefs on Jan. 16, 1994, in an AFC divisional playoff game. Bigger, by far, than any of the previous 82 regular-season games played by the Texans. And that includes the expansion team's dramatic first step into the NFL, a 19-10 victory over in-state rival Dallas in September 2002. Speaking for so many Houstonians, safety Michael Boulware calls today's AFC South clash with the Indianapolis Colts in Reliant Stadium "our Super Bowl.'' Houston is off to its first 2-0 start and riding a club-record four-game winning streak that began with last December's 27-24 upset of the Colts. But Indy is the gold standard for success. The Colts are reigning Super Bowl champs and on the prowl for a fifth consecutive AFC South title. They've led or shared the division lead in all but seven of 87 weeks.
