``NBA Countdown'' serves as the primer for game telecasts on both ABC and ESPN. It features a less-scripted format, highlighted by a lively round-table discussion and debate of the top story lines around the league. Seats at the table are reserved for host Sage Steele and analysts Bill Simmons, Doug Collins and Jalen Rose. The latter two impart wisdom based on many years of combined playing and coaching experience. Doris Burke and Avery Johnson contribute as analysts on the program's Wednesday editions.
