This isn’t really as black and white as you claim. Just as an example this guy here:
Juho Rautanen at eliteprospects.com
And btw, wasn’t even close to as talented as a junior player as Salminen is.
Sure one player has gotten a extended look in what 6 years?
I don't think Jokerit would willingly give Salminen a shot unless they had like 10 injuries in the roster, that's the diffenrence between Liiga clubs and Jokerit, Liiga clubs actually willingly play their juniors without being forced to by injuries..
