Be careful not to look at defense as raw # of points scored, because tempo plays into that a lot. A better metric to look at is points per possession, or the average # of points a team scores each time they have the ball. So far in a limited Big Ten sample size, teams are averaging 1.03 points per possession. Tonight, Illinois' defense allowed 1.13 points per possession, which was...not ideal but not among the bottom 5 worst defensive performance of the Big Ten season so far (that would be PSU's defensive performance tonight).
Through 3 conference games, Illinois is scoring 1.23 PPP )best in the league) and allowing 1.05 PPP (slightly below average). They were a lot better at not fouling overall tonight, but were still allowing too many easy looks on pick and rolls, which still need to be cleaned up.
Actually, now that Indiana played, each team in the B1G has played at least one game, so teams can be evaluated based on their efficiency in conference so far. So, based on net efficiency, here are the B1G standings after each team has played at least once:
