Illinois managed to catch Wisconsin Badgers on the final day of the regular season to share the Big Ten title thanks to a 74-72 win over Iowa Hawkeyes.
Illinois are 33/1 to go all the way and win the NCAAB Championship outright and Wisconsin can be backed at 50/1.
The Badgers led the way in the conference for much of the season and appeared on course to wrap up the title and top seed as they opened up a 10-point lead over Nebraska Cornhuskers, who went into the game as the bottom team in the Big Ten.
Wisconsin lost star man Johnny Davis to injury and he missed the final 17 minutes of the game. That proved to be the turning point as Nebraska rallied and claimed an unlikely win on the road.
Davis picked up what has been described as a "lower body injury" by his team and it is speculated his absence from the remainder of the defeat to Nebraska was precautionary, meaning he may be available for the Badgers' first game of the Big Ten Tournament on Friday.
Wisconsin's defeat to the Cornhuskers opened gave Illinois the chance to draw level at the top of the conference.
The Illini trailed for the majority of the game against Iowa and were 15 points behind at one stage but they rallied late on and went on to claim a two-point win.
Illinois and Wisconsin share the Big Ten conference title, with Illinois taking the top seed and Wisconsin having to settle for second as the two teams prepare for the postseason.
