Go to ESPN Media Zone www.espnmediazone3.com (A Resource for Media Professionals) and read Mark Schwarz's bio... or better yet, save yourself some time, because it's not there.
Maybe Mark's been placed on Administrative Leave by ESPN.
After a brief search, I can't seem to find a wiki article on Mark Schwarz either. Does anyone know where he went to college?
