WHITE SULPHUR SPRINGS, W. Va. — Why bother putting a card in the mail when you can just deliver a thank-you message in person? That’s what the Broncos should do Sunday at MetLife Stadium. Tell the New York Jets thank you. If they spend a few extra bucks on one of those 3D pop-up cards, all the better. Thanks for the high-quality defensive lineman — among the scarcest resources in football — for the bargain-basement price. Thanks for helping transform a defensive front that last year was among the NFL’s worst and, through three games this year, is a disruptive group. Thanks for not only the player but for the ripple effect he’s had on Zach Allen, D.J.
