He did. According to Paul he didn't want to leave but Troy Middleton who was a Lt Gen in WW2 and then Pres of LSU essentially ordered him to go to Army and revitalize the program.
I was 7 and the 1960 Sugar Bowl when we lost to Ole Piss 21-0 (sound like 2011?) in a revenge game really broke my heart.
