I agree Jinky would have been sensational at that world cup. I'm not sure if you remember too much details of Brazil's tactics at that particular world cup but they were absolutely brutal. Because they had been booted off the park in 1966, they had decided the only way to win the WC in Europe was to become extremely physical and went down the Uruguay/Argentina/Racing Club/Atletico Madrid route of kicking the shit out of every opponent.
It is worth a few minutes of your time to check out YouTube for the assaults they inflicted on Scotland in that '74 game (go into about 6 minutes in the link below for a small taster - there is a better/worse "lowlights reel" on a BBC documentary), and as for their battle with the Total Football Dutch glamour boys - well both teams were appalling (it was more mixed martial arts than football). I fear that that Brazilian side could have ended Jinky's career if he had started turning on the style against them.
