I know you admitted to stat watching, but Benning is not close to Makar. Visually, it is just obvious. I have been watching the AJHL since grade one (22 now), and I have never seen a player do the things Makar was doing, but I didn't follow the 2017 draft year too much.
Even statistically, Benning's production was largely driven by PP points. JBD had a much higher EV1/GP than Benning. I can't find any data on Makar, but I'd guess he was well ahead of Benning. Makar had twice the amount of goals as Benning, and JBD had 8 more goals than Benning. The above stats might suggest that both Makar and JBD had greater direct involvement in creating offence.
I'd take Savoie before Benning. I'd have Benning as third-rounder. He can move the puck well (and a lot), and he has good offensive instincts, but his gap-control is brutal and his decision making can be really questionable. Gap-control can be fixed, but decision making is concerning. His physical tools are also nothing to make note of. The best realistic outcome for him is that he is an offensive bottom pair guy that can also contribute on the PP.
I'd be shocked if we drafted Savoie, but if he can learn how to compete at a higher level, he should be able to be a top-nine scoring winger.
