I get that, but it's more of a though experiment of philosophy, not pure numbers.
I'm not speaking purely about draft pedigree. I'm talking about assuming both become impact players, what type of impact player would you prefer? I would venture the guess that Demidov becomes the more point productive person but Lindstrom's size and physicality will also provide value outside of numbers. You could also look at it like this - given the choice, would you take Brady Tkachuk or Tim Stutzle? Stutzle is more productive but Tkachuk bring a lot of other elements that clearly add value.
We've seen teams pass on the big sized guy before - M. Tkachuk is 2016. Matthews - Laine - PLD - Puljujarvi - Juolevi (oof) - then M. Tkachuk. That said, I think Laine and Puljujarvi were well ahead of Tkachuk in the prospect rankings making their selection above him obvious but still, we have a similar situation growing here where there is a clear number and a lot of quality guys in 2-6 and they all bring different styles at different positions.
