In hour 4 of The Drive, Zach and Phil take a deep dive into Sean Payton and the Broncos offense, a day after Davis Webb was announced as the Broncos play caller. Should the Broncos trust a 14-3 team with a young quarterback to a first time play caller in Webb? What will Webb be able to bring that Sean Payton was lacking in? Will Webb's and Payton's offensive philosophies align? We react to Mel Kiper's most recent mock draft in which the Broncos select a safety with the 30th overall pick. How would the guys feel about taking a player that is not a position of need? We wrap up the show with DenverSports.com's Jake Shapiro joining the show to discuss Robert Livingston leaving Colorado to become a positions coach for the Broncos. Is this a sign of bad things to come from the football team up in Boulder?
