If you get out rebounded you will lose the game most of the time. If you look at any games, you will see that the winner usually outrebounds the other team and if one team is more dominant in rebouding, they will win the game by more.
You know, this is very interesting. I decided to test out this method on some other things. Did you know that the team that makes more shots than the other team
also seems to win most of the time? Amazing, the team with more assists ALSO! seems to win most of the time. And this one's hard to believe, but the team that plays better defense and prevents the other team from making more shots, you guessed it, seems to win most of the time!
Point being, more of any skill is ALWAYS better. The question has to be, which is *more* important? In this case, are you suggesting that guards should get more rebounding training at the expense of js, od, pa, etc? I'm not saying I agree or disagree, but I think that's a very unusual recommendation when discussing u21 players who need to maximize their training time, so I'd like to hear you defend this.
