Incredibly 1 win out of 3 could see us finishing top (we beat Leeds, Leeds beat Wigan, Cas drop points in France) and 0 wins out of 3 could see us finishing 6th. Regardless of the standard of Super League, this is one hell of an exciting finish. Just done my own calculations while I had a minute and I've come up with

Saints 40
Wigan 39
Cas 38
Leeds 36
Huddersfield 35
Warrington 33.

I'd have more chance of predicting the lottery numbers than that being right though.

Theres 2 losing teams though. Does it go on who finished higher in the table out of the 2 semi losers?

It's been confirmed on the RFL twitter feed it's the highest placed team in the league table who doesn't make the GF.

This does surprise me - Sky/RFL have not rated the League Leader's Shield (aka Hub Cap) as much of an achievement / trophy.

Any chance of Saints progressing beyond week 1 relies on us losing this week and Catalans doing us a favour. Would give us a home semi against Huddersfield.....which we'd probably lose anyway. In reality I see us losing and Cas winning which would give us a home schlacking off Wigan in week one.

Actually, If Catalans, Huddersfield and Wigan/Wire win, Cas would finish 4th.
