Manny Elk dropped a top 15 drafted prospects post in early July based on a new model. Not suggesting his model is better or worse than a ranking from the Athletic, but it's got math behind it and not just an effort to put names in order.
He had Valimaki as the 10th best prospect on the list, Rasmus Andersson 12th. Fox didn't make the top 15

3rd round picks can certainly gain ground and pass the value of first round picks a year apart, it happens. But to do that you need an epic leak from the third rounder (have seen that), and a fall from the first rounder (haven't) so I wouldn't be so quick to equate or flip them at this point based on one ranking having them close.
