Nah, I'm ok with what happened. Changing anything then, changes from then to now. Maybe for the worse, maybe for the better. There's no telling.
Edit: Thinking about what I would have changed in a draft reminds me of the scene in "About Time" when he goes back to save his sister and comes back to his daughter suddenly turning into a son and he didn't like that time had a cause and effect to it, so he goes back and lets his sister get in a car accident.
Pens needed car accidents to get to where they are, if we had Toews, maybe the team plays so well that Bylsma being an idiot is masked by it and he's fired after far too many seasons later and we've missed out on our latest back 2 back or keeping Jake or Murray or etc.
This ain't Marvel, leave "what would I change" to movies.
