Thinking coaches are like hen's teeth. There have been a few, like Doc Craven, Kitch Christie and Ian Mac. There have been quite a number which you could call good to reasonable.
Thinking coaches try different combinations, ie Doc had 6,7 and 8 in what today would seem slightly out of place. He composed strategies, ie 2 strong heavy weights as agile flankers, ie Jan Ellis, Piet Greyling and sometimes Frik Du Preez ( who was brought over from lock) and fairly medium to light weight brilliant Tommy Bedford who was a no 8. It worked well, 2 construction workers and an engineer.
Kitch Christie, when facing NZ in the 1995 RWC final took Mark Andrews from lock to no 8 and closed NZ's expansive attack and with Joost and it worked.
I think PSDT is played slightly out of position, I think he is lock, indeed and I sense he was better at it. He even out- jumped Matfield in Natal Sharks/ Bulls games. Frik Du Preez was both, but switched when ou "Doc" had a plan.
