Marner to CAR is the best fit I can see. They have the cap space and he fits their play style (strong defensive forwards). I'd ask for Jarvis+Morrow but I don't know if they'd do that - Jarvis is leading CAR forwards in ice time this playoffs. You'd probably have to settle for Drury, Morrow, 2023 1st which is underwhelming but it's the only realistic fit I can see.
Below are scouting reports from Scott Wheeler this year:
Morrow:
He’s an excellent transition defender who transports pucks confidently, plays boldly inside the offensive zone and possesses impressive handling skill for a defenseman. He’s an exit/entry machine who carves teams up through the neutral zone with head fakes, side steps and cuts (his skating really impresses on its edges, even if he’s not explosive). When he’s on the ice, he wants to take over and direct play in possession and does so by guiding opposing players out of his way. And on top of all of that, he’s a 6-foot-2 righty whose game defensively has taken important steps to cut back on mistakes, stay in better positioning and eliminate some bad habits that have often concerned scouts. There’s real top-four upside to Morrow if he continues to round out his game.
Drury:
Drury just keeps playing good hockey at every level (though the counting stats haven’t come at the NHL level yet, his underlying results look really promising). First, it was the USHL. Then it was the NCAA. Then it was the SHL. Then it was the AHL. He doesn’t have dynamic qualities per se but he just looks like the kind of player who is going to become a solid up-and-down-the-lineup, everyday NHL player. Drury has always been known as a driven, 200-foot centre who involves himself in the play, plays within his team’s structure without cheating, works to get the puck back and excels at moulding his game to play alongside talented wingers. But his offensive skill has also developed nicely, with above-average tools across the board as a finisher, handler and passer who can now create offense in a variety of ways. So while his game starts with a strong foundation and sound commitment to the details, there’s skill that happens in between and an approach that takes what’s given and executes.
