Schmaltz is 27 years of age (as of Dec 31, 2023 anyway) and under contract for two more seasons beyond this one. He gives the Rangers flexibility as he can play either right wing or center.
The Coyotes receive a RW project in Kakko, large 22 year old left D Matthew Robertson, and a 1st round pick. With the picks the Coyotes would have at their disposal, they could make further moves to try and improve their roster.
The reason this one may make sense for Ari is that while 27 isn't ancient in the NHL, by the time they are competing for a Cup, Schmaltz will be. This makes them younger, but with a player coming back who is already in the NHL.
