I'm not suggesting that Brown should not have caved, but without knowing the contents of the report, I can't say that he should have, either. It's possible that Brown went to bat for Koenning, and was told that it was either Koenning or him, in which case, caving would have been the only logical thing for him to do. However, we don't know that this happened, and it would be "fanboyish" to assume that it did.
Yes, we don't know but that hasn't stopped you guys from blaming Brown.
