They used also FCP so it can't be the reason? I think I'm done with that defense mode
Your chosen defensive strategy affects how your defensive rebounding works, which is why both teams running FCP saw their opponent end up with 40% offensive boards. Of course, that's a little misleading - Suomi had exactly the same number of offensive boards as Lubnan had defensive boards, with the other missed shots probably in the "fumbled out of bounds"/airball/scramble category. Lubnan had 31 boards while Suomi had 42 defensive boards, which is a slightly less effective performance offensively, just that because they took and missed so many shots, the raw number of offensive boards is higher.
But the moral of the story is, if you want to rebound your opponent's missed shots at a reasonable rate, full court press is definitely not for you.
