With the trade deadline approaching, this always becomes a topic of discussion, so let's see how many moves we can list that can be directly attributed to a team's Stanley Cup win.
The first trade that always springs to mind as being the quintessential trade deadline move was the Islanders' acquisition of Butch Goring from the LA Kings for Dave Lewis and Billy Harris. The Islanders would go on to win their first of four consecutive Stanley Cups, with Goring capturing a Conn Smythe during the Isles' second Cup run.
The Ron Francis trade to Pittsburgh also comes to mind as a significant addition for Pittsburgh that led to back-to-back Stanley Cups.
There have been a few others that have had a similar impact, some of which took place within the same season. Colorado acquiring Patrick Roy and Mike Keane in 1995-96. Then they do it again with Rob Blake in 2001.
The Red Wings trading for Brendan Shanahan in 1996-97 led to back-to-back Stanley Cups, and more down the road.
The most recent ones that springs to mind was LA acquiring Jeff Carter from Columbus in 2012, and then landing Marian Gaborik in 2014, once again from Columbus.
The Ducks landing Chris Pronger also directly led to their Cup win in 2007, although that occurred right before the start of the season.
Reviewing the list of names traded, that's an all-star roster of players who all played a significant part on Cup winning teams. What are there some of the other pivotal deals that I haven't listed that occurred within the season a team won a Cup that should receive similar recognition?
