I'm pleased to see Agar publicly supporting Lauaki. At the same time I'm also pleased to notice that he recognised he has a fiery temperament and other teams will play to that. If I was Agar I'd sit Lauaki down and show him some old videos of Trevor Skerrett playing, especially one of a 1980s semi-final against Cas. IIRC Keith England had given James Leuluali a bit of a roughing up, Skerrett waited his time and hit Beefy with one of the most perfectly timed tackles I'd ever seen. Even a packed Elland Road could hear the "ooooooommmmmmpppphhhhh" as all the air was knocked out of England's lungs.
There's a lot to be said of the old adage: "vengeance is a dish best served cold".
Don't look to retaliate straight away, be patient and wait you time, it will come and when it does, give it back in spades
