He has not “proved to be dishonest”. Eckert authorised something dishonest. That does not prove him to be dishonest. Somebody was saying he lacks integrity, maybe you, maybe someone else. Again not so. You are arguing from the very particular to the general; damning someone’s whole character based on something they did wrong. It’s a logical fallacy.
And I think it does matter what the players think. If Eckert didn’t treat his players with honesty and integrity they simply wouldn’t play for him. Some have gone beyond that and praised him.
