      Sagarin's stuff is a little bit of overkill for the NBA. Doing
      simple evaluation of schedule strength and home/road easily accounts
      for things well enough. Sagarin's evaluation goes above and beyond
      and makes sense for college where varying schedules are huge.

      So, yeah, Sagarin's overall evaluation should be roughly comparable.
      It's just more interesting to look at the offensive and defensive
      ratings separately. Tells a better story.
