If anyone is a reasonable facsimile of Marner, it's Barzal, and he feels more big game and less predictable (not looking to make a pass 95% of the time). He never really comes close in terms of points, he's just a PPG guy for the most part, but then again, he doesn't play with anywhere near the talent that Marner gets to play with.
I would be listening on a deal for him, but then NYI has to pick up at least $2M or $3M more with Marner's demands, which I don't think they'd do, not to mention give us another player too to make up for the seeming offensive upgrade.
