Bottom line for many people is that, consciously or subconsciously, they know that White people will always play "the bigger man" and accept blame or responsibility for the sake of teamwork, while Black people will almost invariably act like spoiled, rotten children whenever they are called on for their BS or ineptitude.
Hence, the sensible, mature White vessel becomes the default container for people's frustrations they WISH they could vent upon Blacks, but they know Black people will actually stand up for themselves justly or unjustly, while White people tend to just turn the other cheek in non life-or-death situations.
Therefore, Conte is blamed, Heath is blamed, etc.
When a White succeeds, which is often, he will almost without question "spread the wealth" of credit. Very rarely do you see a White athlete pat himself on the back.
