UO < Missouri

6/3/2009:
Quoting from this story from Missouri:

A recently released study done by the American Association of University Professors reports University of Missouri salaries for professors ranked second to last out of 34 public institutions studied, ahead of only the University of Oregon.

How far is Oregon behind Missouri? According to this study, $8,300, or more than 10%. (A reader points out this ignores possible diffs in benefit packages. True.)
