John Sadak wanted to be a scientist. Instead he broadcasts NFL games on national radio. The Westwood One announcer joins the PxPCast this week to talk about his journey in broadcasting and how he hones his craft. Sadak not only works for Westwood One, but also for CBS Sports Network and the Scranton/Wilkes-Barre RailRiders (AAA-Yankees) among other outlets. You can find him on twitter @JohnSadak.
