Most important feature for our centres is defense and him and Pompey are probably our best defensive option. He's handled Holmes, Staggs, Farnworth with relative ease. Don't imagine he'll have trouble managing Jesse Damien who has been out of form all year according to the sharks forum.
It might not line up that way on game day but I actually love the second row pairing of Marata/Leka. That is our most damaging backrow pairing on attack. Did a real job on the broncos the last time our back row lined up that way with both wreaking havoc. Can see both causing nightmares if we run them at their halves, neither of which are known for their defence.
Either way, it's a solid team that can win on Saturday. Our pack without JFH/Barney held their own against Canberra, who are much stronger in the middle than Cronulla. So we'll be fine with JFH against Cronulla. Gameplan has to be to bomb to their wingers (especially Hiroti) who have been heavily exposed their last two games against Coates and Tupou. Katoa is coming off a three month layoff without even a pre-season, so he will be very rusty. I'm not convinced he's going to play, with an outside back (Atkinson) on their bench.
He ended Walsh with the opening tackle of the game too

It must affect the other team’s psyche when he does that or send Herbie flying
