It is random in how it weights different stats and not reflecting players peformances as the Barca example.
Terrible idea to point to whoscored ratings ahead of actually watching the players as has been show.
The fact you dont disgaree with much shows you domt watch Barca as Suarez, Pique and Rakitic have been nowhere near three of Barcas top four players.
If you want to use it go ahead but dont expect anyone else to stick to the flawed ratings it produces.
You are the one that doesnt seem to understand.
But it isn't random how it weights those stats. It is either based on human experience or derived from human experience (the neural network approach).
The only reason people think it's a terrible idea is because it's so clinical and objective and people like to think their opinion is "right".
I've watched every Barca game this season and I while I agree Suarez has been poor he has been poor by his standards not an average player's standard. He has scored 2 goals in 3 appearances. For most other centre forwards that would be great.
As for Pique and Rakitic. I think they get a lot of unfair criticism. Pique plays in a defense that has conceeded 2 goals in 6 games all the time playing a high line and being expected to play out from the back even when pressed.
Put it this way. If you don't want those players I'm sure other clubs would.
The one player who is rated very poorly (for his standard) is Iniesta and again while I think in this case it doesn't tell the whole story. What it might indicate is Iniesta gets subbed a lot and his influence is on the wane. Would you disagree with that? Here is a case were the unfeeling computer is saying what everyone just doesn't want to admit.
