There seems to be a bunch of variability here. In support of my original assertion of 150-200k, that site has multiple average debts for different fields in my stated range.
Actually, the article you linked confirms my original statement. Look at the "graduate loan debt" section.
From the article you linked: Average student loan debt for a professional degree from a private, nonprofit institution $243,300
I have no idea how they got 28k when most every number I see on that page is much larger.
All the other numbers you see that are higher are graduate degrees. Comparing a medical student debt (4+ years more of school beyond the 4 of undergrad, residency, perhaps a specialty on top) to only a 4 year degree is not representative of the vast majority of student debt.
