The Texans offense will have its hands full on Sunday in Los Angeles.

The Rams defense is coordinated by a familiar face in Wade Phillips, who held the same position with the Texans from 2011 through 2013. Los Angeles is tied for 9th in the NFL with 19.4 points per game allowed, and the defense has picked off 10 passes this season, which is tied for the 4th-best mark in the League. Texans head coach Bill O'Brien has the utmost respect for Phillips and his defense. 

"He's one of the best of all time," O'Brien said during a Monday press conference. "He's a great defensive coordinator. Wade's one of the best to ever do it."

The Rams are 6-2 and atop the NFC West. They've won three in a row, and five of their last six. During their three-game win streak, they've allowed a total of 34 points. O'Brien described why Phillips and the defense are so challenging.

"It's an attacking defense," O'Brien said. "It's a one-gap defense. You better be ready on third down for a game plan-type blitz. You better be ready for man coverage. Going to stop the run, going to get after your quarterback. Everybody has to be on their A game when it comes to playing these guys. These guys are playing at a high level."

O'Brien and the Texans will practice on Wednesday, Thursday and Friday before leaving Saturday to face the Rams. Kickoff is Sunday afternoon at 3:05 p.m. inside the Los Angeles Memorial Coliseum.
