Heard he's #1 on many teams lists.
How would the Toronto maket react if they take him instead of McKenna?
Slaf vs Wright 2.0, but on steroids
Twitter, Reddit, Facebook, etc would all blow up. It would put so much pressure on Reid or whoever they draft instead of McKenna, because they'll constantly be compared, and McKenna would also hit the NHL first.
So Reid would be playing NCAA next season, while McKenna might immediately put up ~50-60 points in the NHL, creating pressure on him for the next season to try to have a similarly impactful rookie year (which is unrealistic, as defencemen typically take longer to develop). Also, I'm not saying that pressure is fair, or that Reid should feel pressure for a decision he didn't make, but I do think that's the reality.
In saying that, it
might be the right move. The way I see it, there are ~3-4 very VERY good D prospects at the top of this draft, and even in a vacuum id prefer a top D prospect over a top one-dimensional scoring winger prospect, but even moreso in the Leafs case.
I'm also pretty confident we're going to see one or more become a legit #1 D, and a few become solid top pairing / top 4 guys, though also presumably a bust mixed in. Problem is, that's the field, and if you're picking one over McKenna, you have to pick the right one. You don't want to pick the Nemec, Boqvist, etc of the bunch, and frankly if you're passing on McKenna, you don't want to pick the Hanafin/Byram either. You want the Heiskanen/Makar/Hughes.
I'd be more inclined to trade down to 3rd or 4th OA, get another piece or two, and then still get first or second choice from among the D prospects (unless the scouts / draft combine interviews make you think one of them is clearly THE guy to take).
