Wigan will try to blow leeds open early and get a couple of scores in the first 20 minutes. Unless one team completly collapses the game will likely evolve into a very tight arm wrestle, so if wigan post 1 or 2 early scores they will be able to grind it out and leeds will find it difficult to engineer a lead in the game.
First 20 minutes are vital. If leeds took an early lead, like last year then it's well and truly game on.
I'm afraid it will likely be a very tense nerve wracking game. Heart says leeds but with tomkins finnaly announcing he's leaving, home advantage, the week off my head edges towards wigan grinding out a close win.
