Marshall wasn't Div II after the crash they spent a few years in the Southern Conference I-AA before moving back to Div I-A in 97. They were pretty much booted out of the MAC shortly after the crash for numerous violations. Marshall began a streak of winning seasons in 1984 that lasted until 2004, and had the highest winning percentage in the 90s of any Div. I school. The upcoming movie should be pretty inspirational in how the program rose from literally the ashes.
OK -- thanks -- I must have assumed they were promoted from Div II when I saw them in the standings....
