In the second half of Sunday's loss to Indianapolis, the Texans' run defense vanished. It is a problem that is reoccurring.

Against a Colts offense that ranked last in the NFL with an average of 69.2 yards rushing, the Texans surrendered 154, including a 4.5-yard average per carry.

"They tried to pound us in the beginning, but we didn't let them do it," cornerback Dunta Robinson said about the Colts rushing for 37 yards and a 3.1 average per carry in the first half. "After that, it surprised me a little that they'd try to establish the run in the second half, but they did.

"They made the correct adjustments."

Those adjustments led to the Texans getting crushed in the second half.

Peyton Manning finally found a way to get the Colts' offense in gear Sunday. He used the pass to create running lanes, mystified the Houston defense with gashing plays, wore down the Texans with a steady repertoire of no-huddle offense and got his teammates playing at full throttle. This is how Manning believes Indianapolis can win.

The Baltimore Ravens have won four straight, rookie Joe Flacco is showing the poise of a veteran and Ray Lewis looks as good as ever. Scary thing is, the Ravens think they can get much better. Flacco threw two touchdowns and Lewis had a pair of interceptions to lead the Ravens to a 41-13 victory over the Houston Texans on Sunday.
