This thread is confusing. Let me correct this thread. Mark is not a graduate, he is an alumni. He has done plenty of national work, if you consider working for ESPN radio National work. When he was the radio pbp guy for the Mavs. He would do ESPN Radio on nights the Mavs did not play. I haven't heard him on ESPN radio in the last 2 or 3 years.
SMU guy Rich Pkillips (Dick Hicks) is an accomplished PBP man.
Doug Anderson, who does the pbp on TXA21 hs football, also works on College games for the Southland Conference.
They and many others that went through the NT Broadcasting program under Bill Mercer are sucessful because they learned that the score is the most important thing. That is why you can listen to a Mavs game and even though it is on TV, Mark announces the score at-least every 90 seconds.
