Indiana scored its fewest points in a Big Ten game since 2006, falling 58-43 to Iowa on Sunday.
But the numbers that stood out to coach Tom Crean were 39 to 23, as in the rebounds Iowa and Indiana collected, respectively.
"Our job on the backboard was absolutely atrocious," Crean said. "We played hard, they played a lot harder."
Iowa benefited from the extra chances, scoring 20 second-chance points to IU’s seven.
"We got punched in the mouth and just took it," IU sophomore guard Verdell Jones III said. "We didn’t fight back."
Crean hinted at changes, possibly getting rid of the Hoosiers’ three-guard lineup. IU’s starting guards had two rebounds between three players.
