what he believes is right no matter how strongly Anae or anyone else disagrees. He just doesn't do that, and he has a long track record of not doing that. He doesn't hesitate to apply the discipline if he feels it is the right thing to do. He doesn't weigh the cost to the team. He never has.
Now, if Anae could convince Bronco that Koroma's actions did not merit a suspension, that would be different. But you are suggesting that Anae could convince Bronco that even though Koroma deserved to be suspended (in our hypothetical--I don't believe that he actually does), he should not be suspended anyway because it would hurt too much. I just don't think Bronco would ever bend to that kind of argument.
