INDIANAPOLIS — The Colts have no problems with close games — as long as they keep winning them.

Peyton Manning delivered another milestone performance, Joseph Addai produced a second straight winning score, and the Colts found another unconventional way to win when Houston's Kris Brown missed a 42-yard field goal as time expired, keeping Indy's winning streak intact 20-17.

"I think that's the mark of a great football team," center Jeff Saturday said, referring to the close calls. "We've won eight games so far, and we're ahead in our division, which is really our main focus and goal."

The implications of Sunday's victory are monumental.

Indy is the fourth team in league history with 17 straight regular-season wins. New England did it twice — winning a record 21 straight from 2006-08 and 18 in a row from 2003-04. Chicago won 17 straight from 1933-34.

Next week, the Patriots come to town with a chance to prevent Indy from matching its original record.

There were plenty of accolades to go around for the Colts on Sunday, too.

Jim Caldwell became the NFL's first rookie coach to start 8-0 since Potsy Clark in 1930.

Manning, the three-time MVP, tied Hall of Famer Fran Tarkenton for fourth in career victories (125) and became the first player in league history to throw for 40,000 yards in one decade. Tight end Dallas Clark caught 14 passes, the third-highest single-game total by an NFL tight end, and with eight receptions, Reggie Wayne moved past Hall of Famer Raymond Berry and into second on the Colts' career reception list.

A week after rallying the Colts with a fourth-quarter TD pass, Addai caught a touchdown pass, then ran 2 yards for the winning score with 7:11 to go.

The biggest impact: Indy holds a commanding 3<0x00BD>-game lead in the AFC South over second-place Houston (5-4) and is 3-0 against its division rivals. The Texans (5-4) dropped to 1-14 all time against the Colts, including 0-8 in Indianapolis.

But this loss was easily the most frustrating of the series.

After shrugging off the Colts early run and fighting back to take the lead, the Texans had two chances to win it or force overtime. Both failed. Matt Schaub, under pressure from Gary Brackett, was intercepted by Clint Session in Colts territory with 2:13 to go.

Then after forcing a rare three-and-out, Matt Schaub moved Houston into scoring position again only to see Brown push his field goal attempt to the left, leaving some teammates sprawled on the field in disbelief.
