It's obviously not fair to say that the pass to Hayward never would have happened (just as people argued that Wade wouldn't have necessarily ripped Rondo's arm out of its socket if we didn't trade Perk in 2011...yep, I am going there) so that part should be dismissed
Why should it be dismissed? Was Hayward’s injury inevitable, or was it caused by a specific landing caused by a specific play involving a unique situation?
In alternate version scenarios, the theory is that some events are due to happen no matter what, its just sometimes circumstances happen.
I know its fiction, but we are talking about theories here, and not having the certain things set in stone make for a very messy discussion. Example would be IT not getting traded wouldnt cause Hayward's injury, but Kyrie's pass to Lebron causes Horford's 6th foul, which makes us send Morris back in who collides with Hayward and cause a similar injury.
No, its a cleaner discussion if we accept certain events.
footnote: I know a lot of you look down on anime, but you guys should really watch Steins gate, its a very good one.
