You can be predictable if you're good enough at something. A genuine powerback, like Nonu and Kerevi, can beat your defensive line and wear it down if it doesn't crumble immediately. But, the ability to get the ball out, to change the point of attack, that's what separates an average team from a great one. Our team on attack and defence is very solid when things are predictable, but not so much when facing something with any level of dynamism. Our defence against offloads and line breaches looks tier 3, like schoolboys shell-shocked in the face of a level if play they've never seen before. On attack, Josè doesn't like anything unpredictable. The blueprint is all about putting the ball at x through y and so on. Ball control. Our phase play is exceedingly static. Esterhuizen himself offers us that dynamism. Immense power with subtle skill. This omission, as well as the reluctance to elevate RG, it really exposes Josè. Damian is as he always has been, but I can't blame him for being called up. He isn't an unknown quantity.
I must also reference Spies on this topic. A very solid overall player, but lacked the Big Joe pass that frees himself up. One of Joubert's tries in his All Black hat trick was the result of Big Joe causing havoc off the back if an attacking scrum. It's no coincidence that Nonu became more effective and solidified when he sharpened up his passing game.
