42. Fred Warner
Many fans think Warner is low-key and one of the dirtiest players in the NFL. That’s why some Seattle fans hate him more than anyone else in the league. The Rams support added themselves to people with a grudge against the linebacker in 2022 (via Sporting News).

That’s because Warner slammed helmet first into their star quarterback Matthew Stafford. It was a late, dirty hit but Warner didn’t receive any punishment for his actions. The officials missed it but Twitter didn’t and roundly abused the 49ers’ linebacker.
