"Matt is an excellent quarterback," Fisher said during a Wednesday morning conference call with the Houston media. "He's won a lot of games. Personally, I've faced him many, many times and I know what he's capable of doing."
Fisher and Saint Louis are 2-3 so far in 2013, and come to Reliant Stadium this Sunday for a noon CT kickoff. They've allowed 20 or more points in all five games they've played this season, and Fisher believes the Texans will present a stiff challenge in Week 6.
"We're going to have our hands full with their offense, which not only includes Matt's arm, but also includes an excellent running game," Fisher said.
"He's the leader of that offense," Fisher said. "Let's be real here: he did a nice job with them last year, the entire year, and there's a lot of games left."
Fisher expanded on his wariness in facing Schaub and the Texans.
"We have to be disciplined," Fisher said. "We’ve faced obviously some good passing offenses, but this one in particular because, not only the drop-back, but the play-action game is outstanding. This is probably one of our biggest challenges to date."
