Back in the 70s, and even beyond that, there was a firm belief, certainly in England, that you did not need to tinker with the two international formats when it came to selecting teams. There were practical reasons, of a kind, in that it did not seem worth trying to develop a separate side for the few games that were played, sideshow as they were to the main event, and financial resources were a whole lot different. But although there was the occasional exception, usually down to an injury, overriding all this was the maxim that the best players, which for purposes at the time meant Test cricketers, would prove the most adept at cricket played over 60 overs.
