Brussow is a pilfering machine no doubt, but he is nowhere close to the class of McCaws all round play, and behind Pocock on that matter too.
Do you guys look at these other aspects?
McCaw has evolved his game over a substantially longer career than Brussouw. Look at the style of player he once was when younger. These days I would actually class McCaw's game more of that a 6 rather than a seven.
It is the size fetish that gets him discriminated against although the rugby world has so much proof to debunk this attitude. Smaller and lighter players are all over the show holding their own plus some in most cases. Warburton, Tipuric, Duesitour, George Smith, Hooper, Gill, Cane. (please correct me if I am wrong but I think Smith is the only player in that group that is over 100kg) All internationally capped players.
Brussouw adds the balance that the Bokke have lacked for some years in their back row adding pace to the breakdown which is often your weak point.
Sure Brussouw is a pilfering machine but he is also much more as a tackling machine, running machine and a supporting machine.
What is also fair to say about Brussow and the players listed above is they know how to use what they have to maximum effect and all so often larger players tend to be somewhat lazy in this regard. All to often you see them have so much more physical impact through skill than larger players. You also get this happening in other positions but that is a topic for another day. Actually you could have a good thread dedicated to players playing above their weight.
