Updated per-possession statistics after a wild 3 day stretch in the B1G:
Michigan has almost come back to Illinois on the strength of one game. Illinois very nearly has caught Michigan as the top defensive team in the B1G, and is just a half step behind Michigan and Ohio State for the second best offense in the B1G (behind an extremely good Iowa offense).
Michigan, Illinois, Iowa, and Ohio State have been effectively destroying what is overall the strongest conference since KenPom started tracking efficiency. Purdue has quietly taken advantage of their schedule to slip into 4th in conference, but is clearly the 5th best team, now ahead of Wisconsin. Wisconsin is still arguably a top 15 caliber team that has been beaten up by the top teams in this conference (they're still 12th in KP!), and they're going to be a scary 6/7 seed in the tournament when they get to play a team that isn't MI/IL/IA/OSU.
Maryland and Rutgers are still probably safe, though Rutgers is now below .500 in the conference after being blown out at Nebraska.
Indiana has been a strong team overall that actually now has a below .500 record overall and likely won't make the NCAA tourney.
MSU could still sneak into the tourney due to a strong non-conference, but really they have still only been the 11th or 12th best team in conference.
Minnesota has completely fallen apart without Kalscher and Robbins, and hosts Rutgers to finish off the year.
Nebraska has climbed back to respectability in overall margin, though their offense is still the worst in the conference by a significant margin.
