To be fair, Poland being good isn't all that surprising. They had close matches with all top ranked teams before basically just very inconsistent and most importantly, they ended up losing all those close matches... Which, if you can battle all teams but can't get over the finish line in any instance it's just a coaching issue imo.
Even with Turkey they lost like 10 matches In the last decade and a lot of them or tiebreaks are close 3-1s.
This should inspire similar teams like Germany and Canada as well.
Germany and Canada dont have bench, Poland also play mostly with same 7, but they have few more players in rotation.
