I’m not sure 4 games in the middle of what is the weirdest summer in living memory (especially for these guys moving into the bubble) is enough to wash away 5 months and 70 games of more or less solid play.
Especially when it’s in a situation where you wouldn’t expect Kassian to be effective: no crowd noise/energy, vs. a not overly chippy team, and one a line where puck control is king (and not via cycling).
I think had he gotten Chiasson’s spot with Neal and Khaira, he would have looked fine enough. But that’s because Kassian needs to be in the specific situation to succeed. RE: on a line with someone else that likes to cycle (even when he’s with McDavid) be it Drai, Neal, or even Chiasson; Nuge, Ennis, and AA don’t really cover that need.
Thus you have him consistently Leeroy Jenkins-ing on the attack going to the net and corners, while McDavid and Nuge hold the puck in open ice.
Personally I’d staple him to Neal next year as those two seemed to play well together. You also then don’t need to worry about the fit at centre. Frankly, that’s my approach towards all the wings next year (fixed winger combos, and the centres able to rotate between them):
RNH/Yamamoto
Neal/Kassian
Nygård/Archibald
AA/Pulju? (Not as concerned about guessing this one, as it’s the most up in the air. It’s a secondary skill line, Ennis, Marody, or Benson could all be fits here too)
