Hell he might not be the best power forward drafted out of Dartmouth that year.
Thats perfectly possible.
Though first of all, go back 4 years and there is a redline offside rule in place and no transitiong game through the neutral zone to speak of in the entire NHL.
Add the fact that Jessiman is 6'6 and have allot of natrual talent.
He got a very good looking stride for a kid his size, there is allot of room for development there. He also aren't a stiff, got pretty soft hands.
In the end, Jessiman was a bad pick, defenitly haven't developed as expected. But, before having good size was practiacally a presumtion, unless you were big you had to be really special. Today its the other way around, sure its good to be big, as long as you are as skilled as the small guys.
In the old game Jessiman defenitly would be higher ranked then he is right now.
