ALAMEDA — Several teams around the league have responded to subpar play this season by making changes among their assistant coaches. Raiders coach Dennis Allen doesn't see the need to go that route.
Allen said in his weekly news conference that the evaluation process for everyone is ongoing.
"I'm not going to stand up here and say we're making wholesale changes," Allen said. "We're going to look at every aspect of what we do, offensively, defensively and the kicking game, and if we feel changes need to be made, we'll make those changes."
Allen said his team's recent defensive play has been disappointing. They get one issue fixed, then another issue surfaces.
On Sunday, it was the pass defense. Ravens quarterback Joe Flacco passed for 341 yards and three touchdowns in Baltimore's 55-20 win. A week earlier, the Tampa Bay Buccaneers rushed for 278 yards and four touchdowns.
Several times, Flacco found receivers wide open as a result of blown coverages or players late responding.
Veteran defensive end Andre Carter said it takes time for players to jell in a new scheme.
"There's no doubt in our minds that we are a talented team," Carter said, "but being talented and going out on the field and having a high level of productivity, a high level of execution for 60 minutes, is another thing. That's the level that we're trying to be on."
Allen deemed the performance of his defense against Sunday "unacceptable."
The Raiders defense and special teams allowed 55 points to the Ravens. They have given up a combined 97 points and 934 yards in the past two games.
