I’ll add to this a bit. It seems that being an annoying, angry pest is sometimes considered part and parcel of being a good 9. But I don’t think that holds true. Genia wasn’t as good as a player when he got caught up in niggle. Neither was Phipps and neither is White. TJ Perenara is a niggler and pest, but I don’t think that is him at his best either. Going back I always though Gregan deteriorated as a player the more he got caught up in niggle. Aaron Smith is probably the only one who seems to be able to niggle/bustle on the move without it detracting too much from his own game. TJ is probably reasonable and Phipps played better angry to a point but too often went too far and lost his composure. All of these guys play their best when they are controlling the tempo. Generally they are better at pace, but with the awareness to take speed out of the game when they needed to. Genia & White for mine are far better players when they shut their mouths and played.
