BIG PICTURE
Illinois: Coach Brad Underwood's team played its way back into the conference lead behind an incredibly stout defense and Cockburn's strong inside play. The defense played well yet again and Frazier's second-half barrage offset a mediocre day for Cockburn, who was 6 of 13 from the field. It's a combination that could lead Illinois to a conference crown.
Indiana: The Hoosiers have rebuilt their defense-first philosophy under new coach Mike Woodson — and it's worked wonders. But on Saturday, they wore down against a bigger, stronger opponent. Indiana has been on the cusp of cracking the Top 25 over the past few few weeks and now the wait will take a little longer.
POLL IMPLICATIONS
Illinois was poised to move into the Top 15 after beating Wisconsin earlier this week and it only solidified it's case with Saturday's win. The only real question is how high the Illini will climb.
