Historic win by the Aussies.
Stokes, despite his desire for entertaining cricket, has to ensure the real reason for playing is to win. In that respect you've got to nail your opponent, His team didn't do that.
It's one thing to score quickly, but that should be done to ensure you take the game away from your opponent. All he did by declaring in the first innings was to give Australia more time to play their normal game. In the end, his bowlers ended up by bowling 64 more overs than the Australians. That's equivalent to two sessions of play. All that was doing was tiring his aging fast bowlers. If he does the same in the next test, he'd better have plenty of test quality backup.
