The Texans acquired Matt Schaub in a trade with Atlanta on Thursday and said for the first time publicly that Carr's five-year tenure as the starter is over.
"Matt is our starting quarterback," general manager Rick Smith said. "We're trying to help David find another place. We're trying to trade him today, maybe the next couple of days."
The Schaub Era begins with the same cloud that lingered over Carr's final season: Vince Young. The Texans could've drafted the hometown star who led the Texas Longhorns to a national championship, but opted to stick with Carr in hopes he'd finally live up to his status as the first pick in franchise history.
"Yes, we've made mistakes," team owner Bob McNair said. "Not just there, that's not the only place. And we'll make mistakes moving forward. The key is you've got to make more good decisions than bad decisions."
Carr became the face of this expansion team from the time he was taken No. 1 overall in 2002. He won his opener, but the Texans have gone 24-56 over five years, never posting a winning record.
Now, Schaub gets a chance to make Texans fans forget about Young.
Schaub's agent, Joby Branion, said Schaub signed a six-year deal worth $48 million.
Schaub hasn't started a game since 2005 and threw only 27 passes last season. McNair said Schaub brings "the leadership that we think is needed."
"There are going to be a lot more things as the starter that you have to do and handle on a day-to-day basis, as opposed to being the backup," Schaub said.
Schaub, who was a restricted free agent, could have signed with any team, but was sold on the Texans during a round of golf he played with Texans head coach Gary Kubiak on Monday.
"The thing he told me was he was going to do what it takes to be successful, as an offensive team, especially," Schaub said. "It's just an incredible opportunity for me to take the next step in my career, leading a team and running the huddle."
