So he is doing 1,33 points per game currently (and 0.73 GPG). Haven't really been watching AHL that closely. When's the last time someone dominated the league that way? Those numbers are just insane. Can't imagine many other NHL teams aside from Wings that would keep a player down who absolutely dominates AHL. The next year will be his last with the current contract. After that it's either give him a one way deal or ship him out (can imagine there'd be a lot of takers). Btw, the wings' upbringing model does hurt a player's financial status when they are pretty much kept down until they are 110% NHL ready. The players do lose a few years of earnings and I can't see someone getting a great deal after playing maybe one season (max) in the league before getting to the 2nd contract. In this case I don't see how AHL benefits Pulkkinen at all. He has nothing left to prove down there.
It doesn't work for everyone, but there is an inherent benefit to being develop in the Red Wings system. For prospects eyeing long term success (Nyqvist/Tatar), they go through it and get paid out later both in terms of development and pay later whether it be with the Red wings or some other team (Hudler a great example)
For those that can't stand it, they take off early and more often than not find they hurt themselves in the process. Just look at Jarnkrok as a recent example. Looks like he wanted out of the system (threatened to leave for EU) but it seems that he is struggling in the NHL anyways and the extra year in the AHL would have been good for him.
You lose out on possible earnings but the Red Wings system is designed to polish your skills and give you the greatest chance to hold onto an NHL job.
Pulk probably understands this like many others coming before him and it has worked out. Pulk has vastly improved since his draft year and his dominance now in the AHL is proving that the system is helping him reach his potential. If they become better players down the road, they make it up in future contracts anyhow.
