Hey guys, lifelong Attack fan/STH here.
First I have to say I'm so happy for McNiven, he really, really deserves it. Hopefully this is a good sign for this year and he can get his confidence back. Flinn our incumbent starter has surprised but McNiven has a higher gear.
His style of play isn't anything out of the ordinary, he's very much a modern goaltender. Has a great glove hand (for the OHL), and is fairly athletic. Capable of highlight reel saves. Has the talent certainly to become a solid pro.
His downsides? He's quite stocky, but a bit short for the modern NHL. And last season he basically fell apart after getting lit up at the CHL Prospects Game. Something changed about his game and he wasn't the same. Big reason why he didn't get drafted this summer.
The upsides? When he burst onto the scene last year, his stretch of play the first half of the season was unbelievable. Never seen a 17 year old goaltender with a run like that, including Jordan Binnington who achieved great things that year. He was lights out, and legitimately special. The big thing is consistency (as it is with so many young goalies), and coming back to the OHL with an ELC might just do that for him.
As for his status as a prospect, I think he just proved it with this camp that he's a legitimate NHL prospect. However, given how goalies work, and especially OHL goalies, extreme patience has to be exercised. Hard to say where he'll be in two years. I do have high hopes that he'll push out Flinn for the starting job, McNiven has been the favourite of Attack fans for a year now.
