Of course anything could happen.
I'm assuming Leeds will have enough for Hull now, which means we'll either face Catalan or a seemingly fatigued Wigan at home. Beat either of those and it's another boost of confidence and Warrington will not want to be facing Saints in their first GF appearance - with all the pressure on them.
Either way, I'm proud that we've shown finally that this team can man up and expose Wigan's frailties the way they did today. After Saints' first half performance in particular, Wigan should feel lucky they finished the game with a respectable scoreline.
