Difference Margins…Three Weeks into Conference Play: About 20% of the conference games are in the books, enough for the offensive and defensive efficiency (points per possession scored and allowed) margins provide some insight to race so far. I have included strength of schedule (conference games only) to provide a sense of how the schedule may have impacted the difference margin for any particular team.
Overall the margins appear to be behaving, about half of the conference teams have positive margins (offense greater than defense), and seven of those eight teams have winning records. The margins do not correspond exactly to the conference records, and those teams with divergent margins tend to draw out attention.
A few observations:
- Butler’s spot in the rankings is no surprise. Their #1 ranking in strength of schedule suggests the other numbers are going to hold up over the next six weeks.
- Fans familiar with difference margins from past seasons see Dayton in a familiar spot, as the Flyers’ record has typically run either ahead of their difference margin or well behind. This season the margin is far wider (and positive) than the record — back-to-back routs of Fordham and Duquesne are the reason. Expect the record and margin to close in the next two to three weeks.
- Charlotte appears to be the negative counterpart to Dayton. Huge road losses to Richmond and George Washington explain the negative margin, but a strength of schedule ranking of #13 suggest that the 4-2 record so far may be vulnerable.
Upsets and inconsistent play add excitement to the conference race and jumble the rankings again this week. The question is how these unpredictable turns will affect the number of bids the conference garners at the end of the season. And whose phone will ring come Selection Sunday.
- Butler (17-4, 4-2, #9 AP) – The Bulldogs’ stumble (the first since late November) may have given La Salle a boost onto the bubble. Hopefully it will not cost them too much over the next six weeks. Rotnei Clarke is back and Kellen Dunham is blossoming, but the team’s recovery has been slow, especially in holding onto the ball, as they are in 10th in the league in turnover percentage.
- Virginia Commonwealth (17-5, 5-2) – The Rams’ defensive efficiency (points per possession allowed) has been rising steadily (see chart below) since the start of the conference season. In three of their last four games, coach Shaka Smart’s squad has allowed 1.0 point per possession or more (not good). Note that the offensive and defensive efficiency averages are curving towards each other, a trend that began after game #17 (the first conference game). Read the rest of this entry »
