Since this whole thing began they have not acted as I would have expected. I live in Niner/Raider country... Niner's the most popular, by far, but the Raiders would be next and there are no lack of Raider fans in my area.
They didn't discuss it much.. and I'm around many of them daily. Sort of a 'shoulder shrug' reaction on the possibility. I read into that a resignation that it was to be and no use worrying about it... but maybe I was wrong...
When it became official I began to see, for the most part the first time, (some exceptions), some anger. Mostly subdued anger but a few hissy fits. ALL those I have spoken to remain Raider fans but also ALL of them... now that it's official, not liking the move at all. Didn't hear that much before it was official.
Sidenote: Interesting... my son-in-law, his son (my grandson), and me all have different favorite teams and all three moved. Raiders, Chargers, Rams.
