Totally agree with this. We can't expect to win every game, all of the time. Although Saints were depleted, we're an out of form, struggling team. The cyclical nature of professional sport unfortunately means we've now got to wait for our next period of success.

At the end of that 07 semi Saints looked beaten their body language showed it in the final too

I'm not sure about that but there is a huge issue in big games for the Saints club. They would likely have lost the semi were it against any SL club with how they played and the one final they did scrape over the line this decade in 2014 it was mainly down the early send off.

After that i just can't back Saints for the GF despite their huge superiority in regular rounds.

Yep. I just haven’t seen a game from Saints in the past 10 years that looks like a grand final winning performance.
I used to say the same about Warrington until Saturday.
Wigan show the kind of traits needed for a grand final win regularly.

It sets up all intriguing play if series. New format (old format), and I think genuinely 4 teams who could take the title

Yes. Hull have been decent on the big stage in recent times and we all know about Wigans pedigree and with Warrington's display at Wembley on saturday a replication of that at OT would go close to getting it done. Very much looking forward to it.
