I have three related questions that concern NHL trading jargon.
Wikipedia reports "Once an NHL player has played in a certain number of games or a set number of seasons has passed since the signing of his first NHL contract, that player must be offered to all of the other NHL teams before he can be assigned to a minor league affiliate." So, the question is: a player transferred through a waiver is not on loan, but has been sold to a different team before the end of the contract, is this statement correct?
If my understanding of waiver is right, I wonder whether there exist a separate trading institute that allow a player to temporarily change team, such as on loan (i.e. player P goes from team A to team B for a short period, even shorter than a full season, and then goes back to team A). Is there something like that in NHL?
Related to the question about loan, could a player be temporarily transferred to another team only for the playoffs?
