Panarin-Kane I kind of get, because it did work once upon a time. Of course, you have to take into account that that was seven years ago when Panarin was an undrafted free agent and nobody had any clue on how to defend him.
Zibanejad-Tarsenko is just toothpaste and orange juice. You should know that's not gonna work without having to see it.
Maybe Panarin-Zibanejad-Tarasenko, I'd be willing to give more time. Kreider-Zibanejad-Tarasenko is three volume shooters fighting over one puck and nobody to distribute. Again, a coach should know that doesn't work without having to see it.
It reminds me of when CBJ traded for Jeff Carter and did a victory lap over "we finally got a center for Nash." Yeah, nothing-but-shoot Rick Nash and nothing-but-shoot Jeff Carter.
