Scoring 390 and only winning by 50 odd.
Welcome to ODI cricket in 2020.
I honestly can't see how both teams regularly scoring 300+ in an ODI is good for the game, other than inflating the batting averages of flat-track bullies that have been idolized around the world over the past decade. I don't see how this is helping batsmen develop their technique when most of them struggle the moment the pitch or weather conditions offers even the slightest bit of movement for the bowlers.
Despite the ropes being much further in than 15-20 years ago (that's a whole another issue I've crapped on about in the past), the surface area of the SCG is still larger than most international grounds around the world, and yet against 2 of the best fast bowlers and one of the best leg spinners in the world, nearly 400 was scored in consecutive ODIs. Not a good endorsement to get youngsters to take up bowling when ODIs have become nothing more than a longer form of T20, where it has become "Wicket, 4, 6, wicket, 4, 6 etc." The art of building an innings and other tactics have disappeared in exchange for a power-hitting contest.
ICC really needs to go back to one ball used throughout the entire 50 over innings (bringing spinners back into the contest, as well as reverse swing in the last 10 overs), as well as slightly juicing up the pitch to offer more for the bowlers.
Scores in the 200-280 range (especially sub-250) are a more even contest between bat and ball.
