Not sure I would agree, GoCal. I'm kind of in the opposite boat: a former seven-year Cal athletics employee whose daughter wanted badly to play for the Bears and was recruited by them for a couple of years before being "dropped" by Cal and ultimately signing with another school.
By your logic, I should revile everything about the Bears and want to hear nothing about them until my kid's mid-major knocks Cal off in some future NCAA tournament

. But I still have rooting interest since childhood and a curiosity about how things are going in Berkeley.
I'm sure some Cal fans have the same type of curiosity about former Bears currently donning another school's colors.
