haven't watched much avs over past 2 decades BUT years ago during DRW dark days, i followed leafs pretty closely (babcock and half of keefe era).
Marner always stood out as a great talent, who didnt play up to his potential in the playoffs but some1 who could drive his own line from the wing.
With all that said it seemed like their was a consensus rantanen > marner.
while i half expect for marner to choke in the playoffs again (maybe not this year BC contract year), would be hard to imagine him struggling as mightily as rantanen is now if he was traded.
