I can't find anything but on SNY blog that he's coming to actual training camp. You'd think they would have waited to see how he performed at Traverse City before extending an invite
There could be other teams that are looking at him too. And I'm sure they've seen more than enough of him already since he plays with McIlrath.
As far as SPCs go, it won't be an issue. He may only get an AHL contract. Or if he gets an NHL contract, it will be after other players are sent down to juniors, removing their contracts from the 50 limit (McIlrath, Thomas, Miller).
