Nick Bosa isn't the only 49er impressed by rookie quarterback Brock Purdy's outing against the Tampa Bay Buccaneers -- Trent Williams can be added to that list as well.

Although Purdy was dubbed "Mr. Irrelevant," he has been anything but since taking over under center.
Not only did the rookie help lead San Francisco to its sixth straight win, but Purdy also made history as well, becoming the first rookie in the Super Bowl era with at least two touchdown passes, a rushing touchdown and a passer rating of 125 or higher (134.0) in his first career start.
For Williams, however, this kind of performance from Purdy has been expected.
"We've been able to see him since OTAs. We've been able to kind of get a feel for him," Williams continued. "He's a great player, man, so none of this surprises us.
"It's just another day at the office."
