Ignoring most of your post b/c it's all moot IMO b/c the premise your presenting is incredibly one sided, heavy bais in favour of Laine that it's pure homerism. You want to talk wild speculation, doubling Laine value is impossible in a few months training........I can't be so heavily one sided bais in our favour like your suggesting, I just can't do that, IMO it's a waste of time and borderline embarressing to talk like that. That's why I use real stats, real results to talk.......it helps remove any homer bais.
If you want to talk more realistic and say Laine incrementally improves this offseason......ok we can talk about it. But saying he wildly improves (doubling his value), is just a waste of time I'll pass on that conversation b/c we will just waste each other's time.
I would suggest many (meaning multi teams) teams would start by offering their current 1C+ for Eichel.......which in most cases beat out Laine+.........value in a bubble might be closer, but fit is much better then offering a winger as the main piece.
Example of what I mean, I'm ok speculating Laine will score 35+ goals and even get to 75+ points, improving his conditioning, incrementally improving his defensive play. IMO this a realistic & fair expectation regarding Laine improving this offseason. Let's ignore all our other comments and use this as the starting point for our conversation instead of vague comments. How does this compare to your speculation on Laines increase in value? Once we get to a base starting point on what Laine value is then we can talk from there.
