HOUSTON -- Texans quarterback Matt Schaub has thrown five interceptions and one touchdown in Houston's first two games -- both losses.

His performance has left coach Gary Kubiak answering questions about whether the second-year starter is the player to lead the Texans.

Matt Schaub remains the Texans number one quarterback despite two losses to start the season.

Kubiak today reiterated his faith in the quarterback, but said Schaub and everyone else on the team needs to improve.

Schaub was 17-of-37 for 188 yards and three interceptions, with Cortland Finnegan returning the last one 99 yards for a touchdown in the 31-12 loss to Tennessee.

Schaub's early season struggles have fans clamoring for Kubiak to go with backup Sage Rosenfels.

Rosenfels was 4-1 as a starter last season when Schaub was injured. Schaub won four of his 11 starts last season.

Houston on Sunday will visit Jacksonville.
