Some of my favourite players are Czech:
Urbanek (140 points)
Zita (148 points)
Hnizdil (141 points)
My player Sancho is now 135 but I expect him to reach 140. Anyway, i dont believe that counting a player's SOS is the best way to evaluate him, it would be better to do a sort of weighing giving more weight to the most important skills in each position.
