I don't really value Button's opinion much either, but he's plugged in to that world. Regardless, my point is he was 35th on MacKenzie's list which is a consensus ranking from talking to NHL scouts, and in pretty much every consensus ranking he was in the 25-45 range. In purely hockey terms and ignoring everything else he's a perfectly fine and reasonable pick at #31, but I don't really get where the idea this is some masterclass draft steal is coming from. I get that a 6'3" 215 RHD with a big shot and average to good skating is intriguing, but there's warts too.
There's defensive zone + hockey sense issues, he was in Jr. A last year, and a junk league this year. Again, perfectly reasonable at 31 with the rare combo of physical tools, but there's nothing about his profile, track record, or scouting that suggests this was some can't miss top 15 talent that slipped to 31. Maybe he goes in the mid 20s without the scandal but there's always a dman with great physical tools that falls because he was in a weird league or struggles defending.
It just seems like wishful thinking to me.
