I take it you didn't see Featherstone v Sheffield last week then? It was nip and tuck BECAUSE of the bonus point. Featherstone had to win AND deny the Eagles a BP and Eagles needed a win or a BP to maintain their lead in the league. It attracted a massive crowd and one of the best games I have seen all season. I think both sets of supporters would disagree it was a non-issue and did make a difference to who won the league.
Of course, I did, gogledd. I was there. It did add a bit of spice to the end of the game - sure. On the other hand, it made no difference to the positions at the end of the season. Nor did it make any difference last season.
And that's the summary - adds a bit of excitement at the time but, ar diwedd y dydd/tymor, no significant difference.
I have to say, I'd edge towards bonus points if it were my decision. But I'm happy just to play to whatever the rules are. Personally, I don't think four points for a try has added anything to our game - the team scoring the most tries nearly always wins anyway - but I haven't whinged about it for thirty years. Them's the rules - get on with it.
