Yeah I think that's a fairly plausible theory. England has a very good track record. South Africa had Klusener, Pollock and Andrew Hall. Out of whom, Pollock in particular is maybe one of my favorite cricketers ever. New Zealand though probably has the most consistent track-record of producing such players. At one point they had Chris Cairns, Chris Harris, Dion Nash, with Astle and McMillan being pretty handy with the ball too. Then later they had Oram and Franklin, and more recently, de Grandhomme, Neesham. I'm sure I'm missing alot of other names too.
These are probably three teams that always have atleast one fairly good seam-bowling all-rounder around and more than a few to choose from.
