It's rare, but there are players who have blossomed past in or past their D+5 years. Linndholm, Zibenejad, MacKinnon.
Not saying that will happen to Kotkaniemi, but he's having a decent year playing lower lines and no powerplay time, he's a prime candidate for a breakout if given more of a chance. Betting on himself to breakout isn't that crazy.
I agree.
People severely underplay how much relative ice time plays a factor in a player's offensive contributions.
There are economies of scale in giving good players more ice time and people on HFBoards are totally blind to it.
Consider a lot of the interactions between players on the ice can turn into a bit of a rock-paper-scissors affair - defensemen picking up on forward tendencies, forwards testing defensemen weaknesses, etc.
More exposure throughout the game DRAMATICALLY increases a forward's scoring potential.
An example of what this looks like: assuming we're at even strength and holding line matching constant, a good player getting 10 goals and 10 assists with 10 minutes a game will not simply get 20 goals and 20 assists with 20 minutes of ice time, but likely 25-30 goals and 25-30 assists.
