Yeah, I could see them thinking, this team is going to have spacing issues no matter what.
So they can either have them for the first 6 minutes of each half and hope that, along with upgrading the defense/rebounding, their fringe MVP and All-Star caliber stars can mitigate those issues enough to offset the offensive downgrade.
Or they can have even worse spacing off the bench (and they're likely to play them a lot), with a unit that lacks star power to make up for it.
New era granted, but they've also historically preferred to start big.
