The San Francisco 49ers have acquired Trent Williams from Washington for a 2020 fifth round pick and a 2021 third round pick.

The 49ers moved to trade for Williams after Joe Staley decided to retire. The 49ers entered draft week hoping Staley would return.

Neither the 49ers or Williams are in a rush to sign an extension.

"I think the plan was to land him right now and then let the rest kind of work itself out," general manager John Lynch said. "I think it's always an advantage when you get someone in the building, on your roster. Now you've got a chance. We'll get a really good look at him. We'll see where the rest of our team is at, but right now we are just ecstatic that we were able to pull it off at a really opportune time.

"You're losing a great player like Joe at a very critical position, to be able to have everything line up that he was available right then and for us to be able to land him, I think very fortuitous for us, and we're very excited about that."

John Lynch admitted that the San Francisco 49ers discussed acquiring Tom Brady this offseason.

Brady reportedly put out word to the 49ers that they would be his choice if they were interested. Brady grew up as a fan of the 49ers in the Bay Area. The 49ers would have had to make a corresponding move involving Jimmy Garoppolo to make room for Brady.

"When you're talking about one of the greatest quarterbacks of all time with Tom Brady, of course you're going to have some internal discussion," Lynch told Rich Eisen. "And then you hear rumors that hey, he'd like to come home, that kind of thing.

"So of course Kyle and I have discussions. We're always into getting better, so you always look at everything, especially a situation like that. But within a day or two, Kyle and I looked at each other and said, 'You know what, we really like what we have in Jimmy.' We love everything that he brings and we really believe it's a long-term answer. I would tell you we're more convinced than ever about who our quarterback is in Jimmy Garoppolo."

The San Francisco 49ers are fielding trade offers for the No. 13 and 31 overall picks in this week's NFL Draft, according to league sources.

San Francisco doesn't currently have any selections in the second, third or fourth rounds, and they'd like to add draft capital.

After the 31st pick, the Niners aren't on the clock until No. 156 overall in fifth round.
