That’s fair enough except you’re making the same valid points I amI think he's saying all groups together but at different times for each individual group
Say for example all group 1 play at 3.30 on Saturday, all group 2 play at 7.00 on Saturday, etc
Then people can go see a few different games over weekend.
Only issues there could be 2 best placed group winners go directly to semi so top team in last group would know what they'd need to go straight to semi final spot
Same possibly with team at bottom trying to avoid relegation
