You can be wrong about a player, i mean it's not hard. Just that few accept they were wrong and few will be stubborn and keep changing the goal posts for their e-ego.
Just look at Mount thread, people come up with crap like sideways merchant who barely creates anything when he is among the top players in chance creation.
There are many who comes up with posts that they watched player for years or many games, which more often than not is just crap. They would have watched few times without much interest on said player. So it's a lazy opinion on the first place, Then when you are linked with the same player, you start deeper analysis by watching the analysis videos, individual performance videos, relevant stats to see what they bring to the team.
Anyone can be wrong about a player. It should take more than your team being linked to him to be proven so though.
And it doesn’t matter how much you have watched a player. Fans would do well to remember that they are not required to be scouts, data analysts and all the rest. You watch plenty of football, and even without any sort of deep dive, there are players you rate just as much as there are players you don’t- and you don’t need to be a scout to be entitled to feel how you feel about a player you have watched. And everyone has watched enough Chelsea and England games, it’s not as passing as you are making out.
Anyway, if you felt one way about a player, over 3 years, he should at least be required to suit up before you change your mind. I’m sure you didn’t have to do a degree on the players you chose to rate - so theoretically Mount could have easily been one of those, and if he wasn’t, then he wasn’t. Personally, I’ve always rated Mount, and I’m sure have said as much on here at some point. I think he’s a very good player. Just not good enough, I think we could do better.
Nothing about e-ego, it is actually very simple. If you think a player is great, you should be happy if your team signs him. If you think he’s poor, you shouldn’t, and if you think something in between, then your views should be somewhere in between. There is no obligation to be ecstatic if that’s not how you feel. People seem to think it is their duty as a fan to think a player is great because he signs for us. Which is ofd because fast forward one year, everyone thinks everyone is shit. And only then do they realise that they might have even felt that all along. Perhaps they were just being optimistic. Fact is, optimists/pessimist makes no difference to how well Mount does. So at least have and hold your own view on a footballer, otherwise you probably shouldn’t bother to watch football.
People were even putting spins on Weghorst in Jan about how it was a good idea, simply because Ten Hag brought him here. It’s as if you can’t simply say that you are not excited about a signing in this echo chamber. Anyone’s views can be changed over time, nobody’s view means they are a know it all like you are implying. There’s no party line, thinking differently is perfectly acceptable and not argumentative or contrarian for the sake of it. If Klopp rates Mount good for him. He rates Henderson, as does Southgate, but that can never make me a fan of Henderson.
