The whole outrage about LIV seems almost quaint now, like a throwback to a different era. Just let them all back in, let them all play in whatever tournaments they want, who cares, the more stars playing every weekend the better.
I think public outrage would be minimal. I just want to see them all play together.
The issue is probably how you keep the guys who didn't take the money and stuck with the PGA Tour happy. If you're going to let them all back in, I imagine you probably have to compensate them for their loyalty.
