ALAMEDA, Calif. -- A day of cooling off and watching the film didn’t change Dennis Allen’s mind much -- he still thinks his Oakland Raiders have to quickly figure things out after an 0-2 start in which the team has played poorly.

“[There are a] lot of things that we’ve got to get better at,” Allen said Monday, a day after a 30-14 home loss to Houston. “It’s time for us to do it. Talk’s cheap. We need to make improvement, and we need to make improvement fast.”

Allen said the biggest key is improving against the run --the Raiders have allowed 400 yards on the ground in two games -- and improving on third down on both sides of the ball. These issues have kept Oakland’s defense on the field way too long, and the Raiders have been crushed in the time-of-possession battle.

Allen said there are no magic solution. It comes down to deciding to get the job done.

“(The Texans) ran the ball on us when they wanted to run the ball on us,” Allen said. “That’s a mentality. We’ve got to change that. We’ve got to be better there. Until we prove that we can stop it, you’re going to keep seeing it. We’ve got to prove we can stop it.”

New defensive end Justin Tuck spoke to the media on an otherwise quiet day and he had the same message as his coach. Tuck, a 10-year veteran, said his own play needs to improve. He said the defense, which has eight new starters, is taking longer to find chemistry than perhaps everyone thought.

The Raiders player who made the headlines after the loss was future Hall of Fame defensive back Charles Woodson. He said “we suck” and he was “embarrassed” by the team's play. Allen said Monday that he wished all of his players were playing as well as Woodson, who is 37.

“I think that’s something that is spoken out of frustration,” Allen said. “When you watch Charles Woodson play in that game and the effort that he gave in that game and the passion in which he played in that game, it’s a tough pill to swallow -- when you go out there and don’t perform like you’re capable of performing. He gave everything he had in that game, and we have to get more guys playing like that.”

The Raiders’ problems aren’t just on defense. They had four turnovers Sunday -- two Derek Carr interceptions and fumbles by James Jones and Mychal Rivera. Allen said the Raiders are in the position to survive those types of miscues.

“We’ve got to have respect for the football,” Allen said.“We’re not good enough to overcome those types of mistakes.”

Allen said he is open to changing anything, from him calling defensive plays to personnel changes. Still, he said nothing is planned and noted there aren’t any “saviors” on the way.

The Raiders simply have to get better, and they have to do it now.
