There is a significant % of the fanbase that thinks 'WFT' is patently stupid. Whether that was originally an 'eff you' to NFL brass or the most unimaginative alternative in renaming history, other NFL fans openly mocked it - and it deserved mocking. It appeals to some because it isn't 'Commanders'. I mean, why not rename them 'Not the Commanders'?
If you are the Harris group, and decide to rebrand, your most basic hope is that you pick a name the vast majority of fans will support and can live with. I don't think 'WFT' meets that basic requirement, but that's just my opinion. I would actually vote to stay with 'Commanders' if that was the alternative.
