HUNTINGTON — While the NIT has already started, as have the CIT and the CBI, and the NCAA Tournament — better known as “March Madness” — tipped off on March 13, Marshall fans would be well served to step back to remember a great date in Herd history. On March 15, 1947 — 70 years ago this year — Marshall Coach Cam Henderson took eight players to Kansas City a week earlier and came back with a Thundering Herd basketball’s only National Championship of the organization that today is National Association of Intercollegiate Athletics (NAIA) by winning five games in six days.
