They called it correctly. Van Ness took more than one step after the ball left Prescott’s hand then gave him a shove.
Rule 12, Sec. 2, Article 11 provides that a pass rusher is responsible for knowing when the ball leaves the passer’s hand. Roughing the passer will be called if the pass rusher makes direct contact with the passer after his first step (prior to his second step hitting the ground) once the ball has left the passer’s hand, and the pass rusher must be making an attempt to avoid contact.
That Van Ness shoved him instead of leveling him doesn’t make it less of a personal foul under the rules.
They should do away with the “Rules Experts” on the broadcasts. Most of them probably haven’t picked up the rule book in years. Just more blathering to fill every second of space in the broadcast to keep you from losing interest.
The NFL remains the dominant attraction on TV in the United States. Viewership is up modestly since last year, while traditional TV continues to decline. Their product’s reputation and popularity has been impervious to decades of revelations about traumatic brain injuries, drugs, domestic violence, and criminal misconduct.
