      You make a small mistake in your text where you claim that the
      offensive rebound coefficient is higher than that for defensive
      rebounds. Just out of curiousity, what does it look like if you
      force the intercept to zero? [If you have the time and inclination
      to run the model.]

      Thanks again.
