You probably feel superior calling the question dumb.
Hope your superior knowledge of prospects gets you far in life - but I doubt it makes up for your attitude.
The things that suggest Byfield is near Lafreniere: League production. Nearly a year younger.
Those are arguable.
I'm looking for people's thoughts beyond "Lafrenier is better."
If you aren't capable, scroll by.
In terms of production, one thing to keep in mind is shooting percentage.
Lafreniere is putting up 39-24-60-84 with a 12.2% shooting percentage (24 goals on 197 shots, about 5 shots per game), after shooting 17.8% last year (37 goals on 208 shots, about 3.4 shots per game) and 20.5% the year before (42 goals on 205 shots, about 3.4 shots per game). He's shooting more, but the stats suggest he hasn't been lucky (he's put up high shooting percentages on high numbers in the past, so he's not inherently a low percentage shooter). In the NHL, he could legitimately put up a 12% or higher shooting percentage year after year.
Byfield is putting up 38-31-41-72 with a 23.1% shooting percentage (31 goals on 134 shots, about 3.5 shots per game), after shooting 15.9% last year (29 goals on 182 shots, about 2.8 shots per game). He's shooting more this year at a considerably higher clip (and a really high clip in general), which suggests some luck has been involved. There's no way he would shoot anywhere near 23.1% in the NHL year after year.
Rossi is similar to Byfield. He's putting up 39-29-56-85 with a 21.8% shooting percentage (29 goals on 133 shots, about 3.4 shots per game), after shooting 17.6% last year (29 goals on 165 shots, about 3.1 shots per game). Like Byfield, there's no way he would shoot anywhere near 22% in the NHL year after year.
Not saying all their shooting percentages would be equal, but if you normalize each of them at say 15%, here would be their stats for this year:
Laf: 39-30-60-90
Byfield: 38-20-41-61
Rossi: 39-20-56-76
