To start the year I think it's possible some prospects may force themselves onto the NHL roster. But I think it would behoove both the prospects and the Rangers to have it be something where they are not giving them a spot, they should have top win it by a fair margin.
As the year goes on, call-ups, injuries and whatnot can influence their NHL time somewhat. If the Rangers sell at the deadline that will also influence it.
Mostly I just hope it plays out organically, there should be no pressure to play the prospects just because they are rebuilding, the reasoning behind playing them at the NHL level should be because they are ready, they are being put in a position to succeed and they are improving at that level. If there is any question marks about being able to do so, then I'd think the AHL is a fine place for them given there are plenty of vets signed and there is little chance of stagnating their development at this point.
