In a testy press conference with few concrete answers offered, Washington Redskins general manager Bruce Allen vowed to make changes

Allen has gone 28-52 in five years.

The Redskins went 4-12 last season.

"We're going to start a full evaluation of everything," Allen said. "Look into the way we acquire players, looking at the way we coach players, looking at the way the players prepare in the offseason and in-season and make sure we correct the problems There are going to be changes to the way we do business.

"You can blame me. I'm responsible for what happens with this organization. It's my job, no matter who you are with the Washington Redskins, to make sure we have the right people in their jobs. We understand 4-12 is not acceptable to our great fans, and it's not acceptable to anyone in the building. I feel awfully responsible for it. We're going to make sure we hold everyone accountable for everything that happened."

Allen said the Redskins will have $20 million in salary-cap space. Allen said he can handle business operations and personnel operations.

"It's not too much on your plate," Allen said. "I don't mean to be repetitive, but if we can find a winning formula that's going to help this team win, we'll do it, and that includes me. If it meant mowing the lawn out there every day Tuesday, I would mow the lawn every darn Tuesday. I want to win. This is my job, and my responsibility is to try and figure out how to do that."
