Illinois and Iowa are meeting for the second time this season, as Illinois notched a 75-69 road win on Jan. 11. This rematch comes with much higher stakes, as there are only eight teams still alive in the national college basketball tournament. Illinois is a 6.5-point favorite in the Saturday college basketball odds at Caesars, while the over/under is 137.5. 

Iowa has rattled off three wins in the tournament, with two of them coming in upset fashion. The nightcap on Saturday features Arizona, which is one of the top contenders to win the title. Arizona has only lost two games all season, and it is a 5.5-point favorite for its 8:49 p.m. ET contest. Bet on college basketball and more at Caesars with the promo code SPORTSLINEDYW to double your winnings on 10 bets:
