Nickel cornerback K'Waun Williams was the first free agent Kyle Shanahan and John Lynch signed when they took over in February. He didn't exactly talk his way into the building.
"I was with him for one year in Cleveland (in 2014) and probably said, like, three words to him while we were there," Shanahan said Sunday. "He doesn’t talk much at all, and I don’t either when I’m on offense. But I just watched how he went about his work every day."
In September Williams also became the first -- and only -- 49er this year to sign a contract extension, one that puts him under contract through the 2020 season.
