I'm not saying that Buffalo should pull the trigger on this one, in fact I think both fanbases say "no" but if you take points completely out of context, then we should offer Wood + Kuokkanen to NYR for Kakko + Lafreniere, which would be heavily lopsided but based on point totals from this season, it'd be entirely ok.
You completely ignored:
1) The fact that Hughes at that point wasn't even close to being NHL ready.
2) Hughes has vastly improved in terms of eye test and advanced stats,
3) Production has improved significantly this season,
4) Hughes has hit the iron so many times that he can actually put "blacksmith" as his job on LinkedIn (dry joke, I know),
5) Hughes optimally should play with better wingers than he's playing with this season (e. g. Reinhart would be the best of his wingers this year),
6) Hischier played 10 less games than Eichel (but I agree that Eichel's production has been much better),
7) Team control. That's the biggest problem, Eichel doesn't turn us into contender and he is only controlled for 5 more years, if he walks after that we failed rebuild that started in 2015. I'd rather keep this risk in Buffalo
