The Rangers are absolutely ecstatic with Duclair's progress. He was projected to go late 1st early second after his rookie season in the Q. Then his development completely stalled last season. I spent some time with him at training camp and the Rangers were working with him on diet and strength training, as well as some positional issues. He really took to the instruction--it almost was like he hungered for it. He loved being in New York and left excited. I think that he needed some TLC and folks believing in him. His development this season is at least in part the result. The team is rewarding Duclair for his work this season, which feeds right into the attention he needs to develop properly.
Expect Duclair to get a look in camp next fall. He will almost certainly be ready for the AHL, but its not an option. I would be surprised if he sticks in New York, but stranger things have happened.
Now I will give you a more sinister take on the signing. Is it possible that he is desired as part of a trade and the other team wanted him signed before the trade was made? This is pure speculation--I have heard nothing regarding this--but it did occur to me when I saw the early signing that it could be the reason.
