Front Row- You could just trudge around being a big muscly guy laying out runners and carrying the ball up trying to bunt players off. It would be fun to charge into rucks and try and cripple the opposition scavengers. Maybe to make this position a little bit more interesting you could add a ruck button and a cheeky uppercut button. Its true to real life and if i could play as a guy that could roam the field throwing shady punches at the bottom of rucks i bloody well would.

With the front rowers - the juice for this position would be the scrum.
There really is art to a scrum - these days not a lot of people now how the scrum works - the referees don't even know.
Getting the right hit, when to 'lose' your footing - basically putting off the other front row.
Could be heaps of fun if it was done right with enough different options.
