I really hate this for Ottawa. There isn't a whole lot of upside there, and he has no foot speed or hockey sense. He might have an NHL career ahead of him, but bad players get drafted too. Absolutely no reason to trade up there imo.
Oh god, this could have been good for the Sens, but I'm pretty sure they screwed it up hard. This has "big guy who tough but bad at hockey" written all over it. Meanwhile the Leafs got another small-ish but defensively responsible center.
