You can't have it both ways
Before the play in, the gap in records between the bottom half of the brackets weren't as close, you could sit stars and still eek out wins with reserves
The play in changed that. Seeding matters even more than ever and unless you got a clear lead on the next closest team, you played all your stars
It's made casual fans tune in even more and to your point, being under the umbrella of playoff basketball helps cause people are tuning in to see who from the play in is going to make the playoffs
I'm not trying to change your mind so I want to make that crystal clear. I do just want to highlight that this idea has worked and give the in season tournament one more year and that will be just as compelling.
And if Charlotte or the wizards won enough games to qualify, their games would get watched too.
