Or leave him in the AHL where he belongs
McIlrath will be the 7th D if he isn't traded in the offseason (IMO).
The organization has had nothing but good things to say about the kid, and all reports from Hartford are that he's progressing, and my own select viewings of his games this season syncs with that. You don't lose a young 1st round D that's very close to making the big show to keep a guy like Hunwick, even as well as he's played.
He's been staying out of the box, elevating his game in the AHL playoffs, and is in a top pair role there. What else do you realistically want from him?
The Rangers Top-6 D is clogged with vets this season. He was never going to break through this year.
Also, I think the plan when they signed Boyle to a 2 year contract was essentially a bridge to McIlrath being ready to take that slot.
The kid is going to be a NHLer, just relax. He's your classic long-developing, big dman.
Is that what you sign up for in the first round? Of course not, it was a bad pick, but lets try and look at his development independent of where he went in the draft. He's improved every single season since being drafted. Busts stagnate, which McIlrath has shown zero signs of doing. I'm pretty confident he'll be at least a bottom pair, crease clearing SOB in the NHL, and those guys do have value.
