SANTA CLARA, Calif. (AP) After years of playing in a dysfunctional organization in Washington, the difference in the vibe of a winning franchise hit Trent Williams as soon as he walked into the building for the San Francisco 49ers this training camp.

Williams saw a culture instilled from management to the coaching staff to the players and an energy he wasn't used to the past decade in Washington even before the defending NFC champion Niners have held their first real practice.

"Coming where I came from, a walkthrough was a walkthrough," Williams said. "Our walkthrough here was pretty intense. A lot of focus, a lot of attention to detail and guys flying around. You could tell this is a hungry group of guys and I feel like I fit right in."
