He's so damned good, and when you factor contracts... it's really hard to find elite centers with that favorable a contract. MacKinnon had one, but it's over after this season and his extension kicks in. Draisaitl has one, but it's about to expire in two years.
McDavid is cost-controlled and he's incredible, but he's getting full freight for his heroics. Still, that guy? Sure. You'd trade Hintz for McDavid. Beyond CM, though, it's a real short list. I think that's all the OP was trying to say.
Stutzle and Hughes prompt a conversation. Both young, and both great, and both are cost controlled for a while. It's close and probably comes down to your preference. If the Stars passed in both cases, I wouldn't blame them, though.
