What is the single season record for the most wins by a Div.1 men's college basketball team?

Correction

Until the NCAA stripped Memphis of the 2008 season on August 20, 2009 Memphis held the record with a season of 38-1. Unless Memphis' appeal is successful all games in which Memphis fielded an inelligible player, Derrick Rose, will be cancelled resulting in the record being held by the following 4 teams:

Duke [2] (1986 (37-3)), UNLV 1987 (37-2), Duke [2] 1999 (37-2), Illinois [12] 2005 (37-2) and Kansas[1] (2008 (37-3))
