Individual offensive rating is points produced per 100 possessions. The details of this calculation can be found here: http://www.basketball-reference.com/about/ratings.html.
Usage rate is an estimate of the percentage of offensive possessions an individual player uses when he is on the court.
These two are related to one another, in general the more possessions that a player uses, the harder it is to be efficient with those possessions. So if you remember Dallas Lauderdale, you will remember one of the worst looking jump shots in D1 basketball history (this is entirely opinion and should not be considered a fact). He was however, very good at rebounding, and could dunk a basketball. His offensive roll was to set picks, rebound and dunk. He filled this role, didn’t step outside of it and in doing so he amassed a huge offensive rating with a very small usage rate. The other side of that coin would be Ross this year (or Evan Turner, Jarred Sullinger and Deshaun Thomas before him). The weight of the entire offense seems to fall on this one person when they are on the floor. Opposing defenses know this, and game plan accordingly.
This year in the B1G there is an exclusive club. It's players who average more than 25 minutes per game and use nearly 30% of their teams possessions when they are on the floor.
|IA||Roy Devyn Marble||112.8||30.2||30.4|
If you watch too much B1G basketball the way I do, you will have undoubtedly have heard a 3 things this season:
- Aaron Craft is made up entirely of a substance that gives announcers wet dreams.
- Nik Stauskas, not just a shooter!
- Iowa has late game struggles because everybody on their offense is talented, leaving them with no go to guy.
I'm not sure what their definition of a go to guy is, but if anybody in the B1G fits that description it's Roy Devyn Marble. Also of note, Ross fits right in with this group and as an added bonus actually has the fewest number of turnovers among these 4.
The next cut would be players who play more than 20 minutes per game, use greater than 18% of their teams possessions while they are on the floor and have an offensive rating near 120.
|MICH||Derrick Walton Jr.||126.6||18.3||26.1|
This is the group that B1G player of the year will be selected from. Right now that offensive rating and Michigan's win/loss record means that the award is Nik Stauskas' to lose. In reality Aaron White and Malik Smith are both fairly close to him in terms of usage and efficiency.
And here are your Ohio State Buckeyes:
|Lenzelle Smith Jr||98.3||21.4||30.4|
|Amedeo Della Valle||118.4||22.9||8.9|
Well . . .
Aaron Craft plays a lot of minutes.
