* A player named Artturi Lehkonen was traded from the Montreal Canadiens to the Colorado Avalanche a few years ago. He was a good player for the Canadiens, but the Avalanche thought he could help them win a championship.
* Lehkonen immediately helped the Avalanche win the Stanley Cup and became a really important player for them, scoring lots of goals. The Avalanche got a great player, and it seems like they made a really good trade.
* The Canadiens used the players and picks they got from the trade to get other players who they hope will help them win games in the future. It's a trade that will take a long time to see who really won.
