well we 2yrs where they played at the same level at the same age:
Age 20 AHL
Brown: 76gms, 21gls, 61pts (82gms, 23gls, 66pts)
Rackell: 46gms, 14gls, 37pts (82gms, 25gls, 66pts)
Age 22 NHL
Brown: 82gms, 20gls, 36pts (82gms, 20gls, 36pts)
Rackell: 72gms, 20gls, 43pts (82gms, 23gls, 49pts)
and of course, rakell got double the PP time brown did at 22.
Yes and for every Rakell there's a Tobias Rieder, Andrew Cogliano or Andrew Shaw. And to bring it back to Vatanen, he had nearly identical PPG to Brown (in less games) in his 22 yr old season.
