I think Mike that Moz is referring to the need for Spies to show qualities like fight, passion, anger , determination.. ie he needs to man up.
One thing we often forget about Spies. At 108 kgs or so he is about your average size loose forward. Alberts who can get good go -forward is 118 kg. Also, Pierre has bulked up to that 108 kg and is more naturally 103 kg.
He is ideally suited for wing. He showed a great turn of pace hunting down Whitehead and would, like JP (102 kg), be a fairly dominant back with good speed, nice footwork and a fine hand off. Very difficult to stop near the line. Sad he has not found his true niche.
So we would have these two guys and Frans at 110 kg at centre partnered by Serfontein who even now is 97 kg. Tuate at fullback at 100 kg. Now you try running at that lot. Or tackling them for 80 minutes. They would drive you back in the tackle and dominate the collisions.
Goosen and Hougaard (92 kg) complete the backline which would together with our 940 kg pack would ensure the Boks are top dogs in world rugby.
If only the selectors would catch the vision.
