Before the season began, the Las Vegas Raiders had a ball-hawking defense that created difficult joint practices for San Francisco 49ers quarterback Brock Purdy and had a plus-2 turnover differential in preseason games. Now three games into the actual season, the Raiders have zero takeaways and are tied for last with the Minnesota Vikings with a minus-7 turnover differential. In Sunday night's 23-18 loss to the Pittsburgh Steelers, Las Vegas has a minus-3 differential with Jimmy Garoppolo getting intercepted three times, including twice by Levi Wallace.
