Illinois has the #1 rated offense (offensive efficiency) per the Haslametrics site. Iowa State has the #2 defense, just a hair behind Houston.
The data shows that Illinois (for the season) is not that strong at the mid-range game and that shooting 3s is not a big part of their system. Their high rating is largely because they get to the free throw line (rated #2) and are good at converting opportunities for layups, tip-ins, and dunks.
Iowa State is somewhat weak on allowing opponents to get to the free throw line, but is elite at not allowing opponents to score on layups, tip-ins, dunks, and second-chance points.
