These stats are for B1G play only.
1. Pace (possessions per game)
2. Off (offensive efficiency, this is points per possession)
3. Def (defensive efficiency, this is points allowed per possession on defense)
4. Margin (off-def)
Well after the roll Michigan has been on there is a new team at the top of the conference, and it’s Iowa. Iowa has built this mostly during thumpings of Northwestern twice, Ohio State and Minnesota. Michigan on the other hand played better against Wisconsin, Iowa and Michigan State than they did against Minnesota and Nebraska. There are 4 top teams in the B1G and everybody else just isn’t at their level. Offense is still what separates the good and bad: Iowa, Michigan, MSU and Wisconsin play it, nobody else does (with the exception of Minnesota who plays absolutely no defense and held OSU to 0.8 points per possession).
Dean Oliver has his “four factors of basketball success” (http://www.basketball-reference.com/about/factors.html). I thought I’d bring you a little expanded version of this. I broke down effective field goal percentage into 2 point percentage and 3 point percentage. Defensive 3 point percentage defense isn’t really a thing: http://kenpom.com/blog/index.php/weblog/entry/3_point_defense_should_not_be_defined_by_opponents_3p
So you can think of that as a sort of luck factor (although if you watched MSU go under ball screens on Nik Stauskus you can probably expect MSU opponents’ 3pt% to go up).
1. Def (defensive efficiency, this is points allowed per possession on defense)
2. 2pt% (percentage of 2pt shots made)
3. 3pt% (percentage of 3pt shots made)
4. 3pa/fga (percentage of shot that are attempted from 3pt land)
5. Efg% (effective field goal percentage: (FG + 0.5 * 3P) / FGA)
6. Ftm/fga (made free throws divided by field goal attempts, a measure of how large a part of offense or defense free throws are)
7. Tov% (turnover percentage, TOV / (FGA + 0.44 * FTA + TOV))
8. Drb% (defensive rebounding percentage, DRB / (Opp ORB + DRB))
9. Off (offensive efficiency, this is points per possession)
10. Orb% (offensive rebound percentage, ORB / (ORB + Opp DRB))
Ohio State is third in the league defensively largely on the strength of their ability to create turnovers. There is still plenty of room for improvement rebounding and in 2pt% allowed. Wisconsin seems to be the gold standard for chasing shooters off the 3pt line, where Purdue is probably very fortunate allowing so many 3pt attempts.
Michigan’s offense is the B1G's best right now and it is largely due to making 3 point shots. Michigan is decent at avoiding turnovers, and ok at getting to the line (though much of that may be the ends of the Wisconsin, Iowa and especially Michigan State games). They are a poor offensive rebounding team (though they did step that up against Iowa and Sparty), so much of their offense comes down to just hitting shots. Wisconsin is almost a carbon copy the Wolverines offensively (very similar defensively too). Iowa, despite good 3 point shooting, avoids the three point shot in favor of offensive rebounds and free throws. Ohio State is just kind of average in every regard offensively, and will continue to struggle through B1G play until they figure something out.
