For the second consecutive week, the Texans gave up the winning touchdown in the final seconds, this time in a 30-27 loss to the New York Jets on Sunday. Mark Sanchez threw a 42-yard pass to Braylon Edwards down the sideline, setting up a short touchdown pass to Santonio Holmes with 10 seconds left.
The Jets finished with 401 total yards -- the sixth time Houston has allowed at least 400 in a game this season -- but Kubiak said Monday that he saw progress from the defense. He also offered a vote of confidence for Bush, whom he hired in 2007.
"I believe in him," Kubiak said. "We played much better defense. There were a lot of good things that went on. I believe in the guy. We'll figure out a way to get it done."
The Texans sacked Sanchez three times, and Kubiak said Houston's pass rush was better than it's been all season. Houston also forced two turnovers in the fourth quarter to fuel its comeback.
"You get yourself in those positions and you have to close the deal," Kubiak said.
On Sunday, safety Eugene Wilson was late to help cornerback Jason Allen on Sanchez's deep pass to Edwards. The Texans have allowed a league-high 13 receptions covering at least 40 yards.
"We just need to keep our width better," Kubiak said. "I don't think anyone's out there trying to do something wrong. We need to play it better, from both perspectives, from the corner and the safety. Nobody's out there trying to make that mistake."
Holmes beat Quin in the end zone on the next play for the winning score. The Texans have given up a league-high 25 touchdown passes.
"There are no excuses," Kubiak said. "We're struggling back there. Statistically, that's where we're struggling, so people attack us that way."
Despite the late breakdowns, Kubiak said the maligned secondary showed improvement on Sunday. He liked what he saw from rookie cornerback Kareem Jackson and from Allen, who saw his first action with the Texans after he was cut by Miami two weeks ago.
"You give up a couple of plays late in the game, it negates everything that you did that was positive," Kubiak said. "If you get beat, it goes back to the two or three negative things that you did. When you don't win, it's not good enough by everybody. But there were some guys doing some good stuff."
"We sure as hell aren't giving up," he said. "There's a lot of football left to play. We're going to play a bunch of division games. We get ready to play this week, a big game against Tennessee here at home.
"The effort's good. Obviously, we need a win with the effort."
