He also helped to piss off the West Indians which made for some brilliant cricket.

When he returned to England, Greig caused more controversy in the lead-up to the 1976 series against the West Indies. Appearing on television to discuss the coming summer, Greig's ebullient oratory created controversy when he expounded the West Indies players' reputation for wilting under pressure:
I like to think that people are building these West Indians up, because I'm not really sure they're as good as everyone thinks they are. I think people tend to forget it wasn't that long ago they were beaten 5-1 by the Australians and only just managed to keep their heads above water against the Indians just a short time ago as well. Sure, they've got a couple of fast bowlers, but really I don't think we're going to run into anything more sensational than Thomson and Lillee and so really I'm not all that worried about them. You must remember that the West Indians, these guys, if they get on top are magnificent cricketers. But if they're down, they grovel, and I intend, with the help of Closey and a few others, to make them grovel.[20]
