Rangers are at 44 contract out of the max of 50.
They'll likely keep a couple of those remaining spots open for the just in case stuff.
They will probably sign a couple more inexpensive players whether for the NHL or AHL.
I am surprised some team has not signed Motte yet, maybe he is waiting on the Rangers to figure out how much NHL cap space they'll have, after Kakko, to see if there is an avenue to staying, or he is just asking for too much for any team he would sign with to accept.
Personally I think Motte adds more to the Rangers than many others do. He'd be a very good 4th liner who also could PK if they would play him there. I'd gladly see him on the team over Reaves, Hunt, (probably Carpenter too) depending on match up, and especially in the playoffs.
