NBC Sports 49ers beat reporter Jennifer Lee Chan joins the show to discuss the pending Brock Purdy contract extension. Chan says that the 49ers are going about the extension the correct way after last offseason, which had a lot of drama. Chan says that the 49ers are happy with their offensive line within the building, even though it is viewed as a weakness. Chan is questioned if the 49ers' window has closed or if they have one more run in them
