Definitely Tahu.
Basically confirmed how big a drop-kick he is in a single play and deserves to be rubbed out for some time. If the NRL is serious about removing kneeing, headbutts, grapples and so on out of the game, they should consider handing out lengthy suspensions. An incident such as Tahu's is definitely deserving of six weeks. It was a blatant cheap shot and a terrible look for the game.
Still on Tahu but I've always considered him one of the most overrated players in the game. A very good athlete, especially in his day, but even in his prime he always had a dead-s**t mistake in him and the amount of media hype, especially from the Newcastle fraternity was sickening. Best centre in the game before he left? Piss off.
