I agree with the general sentiment, but a couple of those teams will put up quality in that timeframe and we'll be nowhere near it, even if it is not obvious who those teams are right now.I don't think that will be the case as outside of India most of the test teams across the world are pretty average.
England are too busy drinking in there own bathwater with Bazball.
What we will see and seeing now is the standard of batting in test matches disintegrate across the world.
India have so much talent they could pick 3 teams. Its amazing we have beaten them in big one off games that has probably prevented a dynasty.
I still can't see countries like Pakistan, West Indies, Sri Lanka winning a series out here.
New Zealand have the ability but for some reason just melt when they see a baggy green cap.
South Africa always trouble us but barely play test cricket.
I imagine this is what the post Chappell, Lillee, Marsh era was like.
