San Francisco 49ers star George Kittle sends a warning to the NFL over the return of Robert Saleh as defensive coordinator.

George Kittle is an offensive weapon for the San Francisco 49ers, but he issued a warning to the rest of the NFL about their defense in 2025 with Robert Saleh back as defensive coordinator.

49ers' George Kittle on Robert Saleh Return: 'Violence is Coming' originally appeared on Athlon Sports. Since Robert Saleh left to join the New York Jets, the San Francisco 49ers have struggled to find a consistent defensive play-caller.
