James Tedesco and David Klemmer for NSW; Cameron Munster and Josh McGuire for Queensland.
These are the two players from each side that the opposition will need to shut down. Success in those missions will go a long way to seeing which state hoists the 2019 Holden State of Origin shield on Wednesday night.
For Queensland, the most important thing is not to let the NSW fullback run.
James Tedesco has been superb in games one and two. Coach Kevin Walters and his team need to come up with a plan to shut down Teddy.
That might then help the Maroons control the NSW back five because they are a fine group of footballers. Wingers Josh Addo-Carr, Blake Ferguson and centres Tom Trbojevic and Jake Wighton love running off Teddy.
Nullify the first tackle on the kick-chase so NSW don’t get to open up their bag of skills.
Secondly for Queensland to win, beware of the wounded bull in David Klemmer.
He is going to come to ANZ Stadium with every fibre heightened now that he has been recalled for the suspended Tariq Sims.
Klem was overlooked initially for game three, but considering his performance in game one he will want to show on Wednesday night why he deserved to be there all along.
So his play-one with the ball in each set needs to be curtailed. He is dynamite off turnovers and his post-contact metres are dangerous.
His ruck speed is a big influence in controlling the play-the-ball by NSW for the rest of the set.
And 'Big Klem' will be on a mission so expect something big from him.
I'd advise NSW to keep on their toes when it comes to the Queensland full back as well.
Munster can play both sides of the field but generally carves up the left side with the Storm or the Maroons.
He has great ability at No.1 and I believe he is a lot more dangerous proposition for NSW at fullback because it gives him more space to run in.
NSW will have to do a really good job on their kick-chase to nullify him. He is a difficult runner to put down.
And when you’re talking about the start to Queensland's sets, he's very quick in the play-the-ball.
You give him room to move and, with the footwork he's got, he will give any side momentum off the kick-starts.
Munster is a big body, he has a strong base on him which makes it easier for him to change direction and fend off attackers so well.
He is fairly unique with his abilities – he's got a great passing game and he's a great runner.
So at fullback he'll be able to display all those skills.
Munster is one player NSW won't like facing on Wednesday night. The other would be if Queensland has a real forwards leader that breaks some ground up the middle and shows aggression in the face of the NSW pack.
Match: Blues v Maroons
Game 3 -
Venue: ANZ Stadium, Sydney
That could be either Matt Gillett or Josh McGuire – but I'm thinking that forward leadership probably has to come through the middle so McGuire is your man.
He's been criticised from pillar to post for his dirty play, but Queensland needs his aggression in game three like Petero Civoniceva, Steve Price, Nate Myles or Michael Crocker – that tough nut with that hard edge.
McGuire plays at No.13 and has great ability to clean-up defensively. If Queensland is to win, then they need Josh to lead that forward pack.
