In my view the 'greats' of yesteryear were neither better nor worse than the 'greats' of today. A good angler, whether sea, game or coarse, specialist, pleasure or match, is a good angler.
Any of the good anglers who turn their hand from one type of angling to another make the transition effortlessly and catch more than most.
It's a case of having that 'feel' for it; that instinct for catching fish that some anglers have and some haven't.
The best anglers are usually untidy with their tackle, don't care a great deal about it, but know exactly what to do to catch a fish from a certain swim, even swims they have never seen before.
There has been talk of such anglers having a sixth sense about these things, which I don't know if it's true or not, but such anglers certainly seem to be more in tune with what is required to put fish on the bank.
Perhaps that hunting instinct from thousands of years ago is stronger in the 'great' anglers than in the rest of us.
