Can't see it being a slaughter at either side's hands. I believe the Force have a superior off-loading game to the Reds, probably the best in the country. Reds should have superiority at scrum time in the early parts of the game, but I can see the Force finishing with the stronger scrum when replacements are on. Reds scrum will be a bit of a mystery with ASY (Angus Scott-Young) in the second row. That could also play into the Force's hands.
Force should dominate the lineouts based on form so far. All going well for the Force, they could actually have the best of possession throughout the game. I don't expect the Force to run out of steam as they appeared to do against the Tahs. They are one of the better coached sides in the competition and I'm sure Sampson will have addressed that issue during the week.
Reds could have the better of the tussle out wide, but that relies on the ball getting out there with time and space for the bigger, perhaps better wingers to work with. Much otherwise will depend on whether the Reds backrow get over the top of the Force backrow. Assuming the Force get at least equal share of the ball, then I am starting to think this could be a boilover.
