In hour 4 of The Drive, Zach and Phil dive into the Broncos running back room and the work they have been getting at training camp. Which running backs will be on the outside looking in when the roster is reduced to 53 men? Has anyone emerged as the clear cut wide receiver two? Should we be concerned that Bo Nix hasn’t thrown an interception in practice yet? Is Nix being aggressive enough with his throws? We wrap up the show with DenverSports.com’s Will Petersen joining the show to discuss who the Broncos wide receiver two will be and if it’s necessary for the Broncos success.
