The NYC radio (http://boards.radio-info.com/smf/index.php?topic=159260.0) and Philadelphia radio (http://boards.radio-info.com/smf/index.php?topic=159254.0) boards already brought the subject up, but also, Michael's Sports Machine show was notable for those watching late on Sundays who didn't yet have cable (for the ol' Nick/Fred banter on CNN, and later the up-and-coming SportsCenter) looking for a good wrap-up of all that went on in sports for that day/weekend. Michael covered sports for 28 years for DC's WRC-TV.
