Responding to stuff in the previous thread:
Marner and Hanifin are interesting studies in peak upside, middle upside and floor potential, which makes them a comparison we'll likely have to live with for as long as those Sakic/Richardson comparisons.
At peak upside, I think Marner trumps Hanifin: it's like comparing Kariya/Lafontaine/Kane to Ryan McDonagh...
At middle upside, I think Hanifin has a more useful middle zone if he's more like an Erik Johnson/Jay Bouwmeester who brings elite skills but not consistently elite in performance, while Marner could be a Jeff Skinner.
If they both semi-bust, Hanifin is a useful stop gap on a third pairing, but Marner is likely lighting up the KHL.
