It just comes off as sour grapes on his part and don't forget the glaring Globe piece that just happened to be written by a non-hockey write as @Fenway pointed out. There's a lot we don't know about here but there's some smoke that all was not well with this kid
And I'll just add that he is a young guy, and a jock at that- not the best combo for perspective and maturity . He is probably disappointed about how it all went, to be honest. Unmet expectations and all that. He came in with great fanfare after a strong Olympics, scored some goals early on and was looking like the real deal. Then reality sets in with the hard work of an NHL season against players that are far better than any he's ever played against before and it stopped coming so easy. He didn't exactly light up Providence either, and those were a better class of player than what he'd been up against on a regular basis before. Frustrated, disappointed, going from the star of the show his whole hockey life, to just another rookie in the NHL finding it tough sledding early on and not getting his tired pumped at every turn. Kind of hard to blame him all that much.
