Well that's foolish of you.
Obviously there's some nuance here. I think the step that Laf has to take is far less than the step that others have to take, but yeah, I think he has to be even better, still. I wouldn't say he's been "absolutely dominant."
He's been very good and has solidified himself here, but, if nothing else he needs to finish a good deal better. I think it's definitely fair to say the analytics in that checklist probably don't take bad luck into account and so are slightly flawed, but it's slightly off, not radically off.
Same goes for Miller. I think he needs to be a little better and eliminate some inconsistency, not a ton better. But he needs to get better.
This isn't to say those two should be replaced. They are eventual solutions, not problems.
