Hello, i´d like to know where i can see, read... articles, books, videos (in internet if can be it) about tactis, about where the players should be on the field...... thank you
My key advice is to just watch a load of rugby and really focus on the position you are playing.
Are you currently playing? If so, what position, and where at (what team, what country, ect...).
Ask us some more narrowed questions to get better answers, but at least there's a start for you.
