The answer ?
I assumed that it was because they had better players & were well coached.
You seemingly know something about Trinity that others on this forum don't know.
Perhaps you could give us the benefit of your inside knowledge ?
I'm sure that Trinity's secret of success would be welcome knowledge to other schools who wish to emulate them , ( i.e. assuming that it's a secret that they don't know about & haven't already used ).
I think your assumption is correct. The coaches are better now and they do have a good bunch of players coming through at the right time. However, that does not guarantee success. Remember at the beginning of the season some thought they had nothing to offer this year so obviously they got better as the season went on. Debrecezini being fit was massive for them as he orchestrated the backline like a puppeteer. I guess it helps when you have the Australia A fly half calling the shots. I played at West Harbour for a short while when his Dad was still playing. Thoroughly nice bloke and coached the juniors there. I would not be getting too worried about Trinity's success as it is only one year. Remember, Barker was undefeated last year and Knox was undefeated in 2008. Anyway, I think it is good that schools that don't usually challenge in the CAS start to ramp it up a bit. It makes the CAS stronger and hopefully have more depth to challenge the GPS superiority complex. Better, to have 6 strong CAS schools to choose players from than one or two.
