To be honest, I'm never that fussed about the ratedness of famous players. By the time I reach the level where I could sign the likes of them, the real players have long retired. An advantage of playing the LLM way.
But even if I would play let's say Ajax, I can't imagine I'd even notice if KJH had finishing 18 or 20. As if I'd be able to come up with tactics that could squeeze that last bit of ability out of the lad. Gnooti seauton
As far as I see it, the game has enough randomness in it to forbid that sort of nano-micro-management anyway.
