Some personnel is shared between the two units; for instance, certain CBS play-by-play announcers (e.g. Don Criqui, Dick Enberg and Ian Eagle) call select Sunday afternoon games throughout the first several weeks of the season on CBS and then switch to Thursday and Saturday night games on Westwood One. Boomer Esiason, who is an analyst for CBS' The NFL Today, called color commentary on Westwood One's Monday Night Football (and would often advertise the latter on the former, as ""the Monday night game on Westwood One""); conversely, Steve Tasker, a color commentator for CBS's Sunday afternoon coverage, served as an analyst on The NFL on Westwood One shows.
