Phillips: Keenum is going through a 'rough time'

One day after he was critical of the offense in the 25-3 loss at Indianapolis, interim coach Wade Phillips had not changed his opinion.

“We didn’t play very well,” he said today at his weekly news conference. “We have to play better.”

For the first time since they lost 34-3 at San Francisco in October, the Texans produced only three points on Randy Bullock’s 49-yard field goal.

Quarterback Case Keenum, who suffered a sprained thumb on his right hand, finished 18-of-34 for 168 yards. He threw two interceptions and no touchdown passes. He was sacked four times, including once for a safety. His rating was 42.3.

“He had a rough game overall,” Phillips said. “We’ve got to see the things that he’s done well. He’s made good plays. We have to go with those and eliminate the ones that he’s not doing well.

“Sometimes young quarterbacks have to hit rock bottom to bounce back up. Some of them don’t bounce back up and don’t end up good quarterbacks. This is a rough time that he’s going through.”

After the game, Keenum was hard on himself and took the blame for the offensive failures.

“Yeah, he’s a great kid,” Phillips said. “I think he takes the blame for everything, but we’ve got to help him. He saw the blitzes when they were coming, but seeing blitzes and getting rid of the football is different than just seeing them.

“That and reading coverages is not an easy process, especially for a young quarterback to know exactly where to go with even though he goes through it over and over in his meetings. We practice those things. We’ve just got to find the things that he really does well, and we’ve got to stick with those because we’ve got to move the football.”

Not only did the Texans fail to score a touchdown, but they also didn’t even reach the Colts’ red zone.
