I don’t know how to read this, please splain.
No worries, the "NetRtg" is essentially the same thing that KenPom calculates and uses to rate team offense and defense. The points the offense scores gets indexed to 100 possessions to standardize. The points the defense allows, the same representation.
NetRtg is the difference between Offensive Pts per 100 (scored) - Defensive Pts per 100 (allowed)
Each site adjusted those numbers for pace of play, the strength of the oppenent, a "luck" factor (did the team have a very hot shooting night that deviates from their average?), etc.
HoopExplorer NetRtg generally tracks similar to KenPom NetRtg, but they will be slightly different.
But can think of it as apples-to-apples comparison, just 2 different varieties of apples.
So, look at the circled NetRtg stats:
When JRoss has been in the lineup, our team has had an Adj NetRtg of +51.7. When he's not in the lineup, we are at +30.8. The offense is more efficient (139.2 AdjPts/100 vs. 134.5 Adj Pts/100), but the defense is really different (87.5 AdjPts/100 vs. 103.7 AdjPts/100).
When you look at the overall NetRtg in KenPom, you can see that the "elite" teams have overall NetRtg in the 30-40 range. Here's up-to-date KenPom:
Of course, it's not
all due to JRoss, but the point is that he's really helped our O and D to step up in the NCAAT.
JRoss lineups have been very elite.
