EAGAN, Minnesota — Never mind that rookie cornerback Chuck Demmings has been getting some reps with the starters. “I really think about it like a snowball effect,” said Demmings, who was selected by the Vikings in the fifth round of the 2026 NFL Draft out of Stephen F. Austin. That explains why Demmings got some run this week in the absence of veteran cornerback James Pierre. Obviously we’ve got some really good receivers, so he gets a lot of good work against the guys we have on the roster.” “I can’t speed up my tempo because, ‘Oh that’s Justin Jefferson out there,’ ” Demmings said.
