If we win tomorrow and Wigan and Cas lose we can't lose top spot.
Well we can hope.

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.
