I would think teams are much more sophisticated in their scouting and player analysis than this. It seems to me the Jets are taking advantage of their strong play of late where the are solidifying a playoff spot to develop Niku's game with the Moose. I expect at some point this season we will see a more complete player up with the Jets. A player that will be very important for us in the future.
I think players get reputations that affect how they are perceived. Reputations are acquired in a variety of ways, not necessarily valid ones.
Some of our grab bag D men have performed unexpectedly well but any other team can still see that some pretty lowly regarded D men are playing big roles for us. Add to that that the trade price for AHL prospects is usually pretty low to begin with and I don't think we get much for Niku.
If Maurice would not give Niku a chance earlier this season why would he give him a chance later this season? Doesn't make sense. We have had several injuries to D men that have created opportunity to call up Niku. It didn't happen. Maybe if we get several simultaneous injuries he will get his chance. Or maybe he will get the same kind of chance Spacek is getting.
