At the risk of getting a ton of hate... am not sure Morgan is that big of a genius. He’s been fortunate to have a great team (like ponting), but is he really a master tactician? The change in Eng ODI fortunes was not his initiative - he was merely implementing the new vision of the whole set up. He has done that very well, but I wouldn’t put him in the same league as:
Ranatunga (who completely changed ODI cricket, and took a “minnow” to undefeated WC glory),
Imran Khan (totally turned ODI bowling on its head by picking genuine wicket takers instead of “run savers”),
Stephen Fleming (took a modest team and helped it punch well above its weight),
Martin Crowe (true innovator as ODI captain - remember Deepak Patel and Mark Greatbatch?)
Morgan is one of my favourite cricketers to watch, but as a captain, his “this is how we play” approach has backfired at key moments (such as the Champions trophy). Not very adaptable to non-road conditions.
