Not sure either side won this deal(this is more of a case of lost less) but the Penguins ended off better then the Caps with the Jagr trade
they definitely did not.
I'm assuming you mean because of how awful the team was and the eventual by-product of getting the lucky pingpong ball for Malkin and eventually Sid. But the products of the trade:
Kris Beech: 27 points in 85 games over three seasons. He actually ended up back on the Capitals' roster in 2006 and 2007 and then even came back to Pittsburgh for a week or so in 2008.
Michal Sivek: 6 points in 38 games during the 2002-03 season. Spent another season with the WBS Penguins the following season and was back in the Extraliga by 2004-05.
Ross Lupaschuk: brief cup of coffee in 2002-03, scoring 0 pts in 3 games. Stayed in the organization, skating with the WBS Penguins, until 2005.
Jaromir Jagr: 45 points in 46 games. I should probably mention those stats are only his final season numbers with the Caps before he was traded to New York in 2004. Jagr literally outscored all three products of the Jagr Three in a partial season. And yes, I understand the circumstances of the trade: financials; GMCP looking for cash, prospects, and the ability to tread water until the arena situation had more certainty.
