It often feels like when people say to swing for the fences, it means to go for a flashy player, one with high risk, who's still actually farther from the pro game than his peers, of which many don't end up doing much of anything. Having a pro game isn't a negative, it means the player often has a lot less hurdles to translate his game.
As an example, I wouldn't consider drafting a Stutzle as a high risk pick. He was skilled, but if you looked at his game in the DEL, he was making NHL plays and converting his skill plays against guys with a decade of pro experience. Drouin was a high risk pick and a brutal one. Tkachuk was a "low" risk, he also already had a pro game with a lot of physical growth.
Just pick the player that projects the best.
