I suspect that lower Q players are punished less in ratings for mistakes if they are so lacking in quality that they're not expected to get to stuff.
agree to that.
Also I 've accepted the idea that there 's no place in t11 for GKs like Cech, Neuer or Casillas (ok, few years ago ).
A great GK with rates of 8 or 9, in a very good team.

My pragmatic approach is from a simple cost benifit analysis.
agree to that too.
That's why I buy only one scout/list every season (avg - some seasons none, some 2). It's the gift of the sponsor to the coach
