The RWC is a bit of a bigger deal than the 4N
However, I agree with you, the BBC really didn't trail the 4N very well at all. I was fortunate that I saw the highlights of the 4N final as I was waiting for the RU internationals. Glad I did, cracking final.
Bigger than a new fangled, hybrid game of netball that is being tried out in schools? That got a full 5 minutes of coverage, yet the 4 nations final, about to be kicking off and covered live on another channel of the BBC got zilch. Absolutely nothing. If you think that that is ok, then fine. I don't.
