Golden point (or even golden try) is such a shit concept, particularly in regular season.
What I hate about golden try is that you're taking out two legitimate scoring options - field goal and penalty conversions. Essentially, you're f**king with the rules and the way the game should ordinarily be played.
Regular season matches - 80' and that's it. If scores are tied, it's a drawn match and 2 competition points to each team.
Finals - 80'. If tied, then it's 10' each way. If tied at end of extra time, then golden points.
The NFL have revised their overtime procedures in recent seasons. It was similar to the NRLs golden point with teams winning it on field goals.
Now, the first team to receive the overtime kick off can't win by merely a field goal on the first possession. They have to defend it as well, I.e., the opposition have possession as well.
Personally, I think the NRL should just play a mandatory extra time in finals if scores are tied. Most times, it'll be sorted out in that 20' period.
