Brassard was drafted in his second year of draft eligibility. He was eligible to be drafted in 2016 but was passed over. So if you want to compare the two players you should really be comparing their 18 year old seasons or their 19 year old seasons rather than their D+1 seasons.
18 year old seasons (including playoffs):
Brassard: 73 GP, 13 G, 23 A, 36 TP, 0.49 PPG (OHL)
Juolevi: 72 GP, 13 G, 37 A, 50 TP, 0.69 PPG (OHL)
19 year old seasons (including playoffs):
Brassard: 72 GP, 17 G, 37 A, 54 TP, 0.75 PPG (OHL)
Juolevi: 44 GP, 9 G, 12 A, 21 TP, 0.47 PPG (Liiga) - Still playing
My advice: Be excited about how well Brassard is performing for a 7th round pick. Be excited about Juolevi putting up historical numbers for a U20 defenseman in the Liiga. Take it easy with the disappointment and hate surrounding Juolevi... It's getting a little out of control. Guy is a fantastic prospect.
