On July 3, 2006, the Oilers traded Chris Pronger to the Ducks for two players and three picks:
Joffrey Lupul
Ladislav Smid
2007 1st-Rounder
2008 1st-Rounder
2008 2nd-Rounder
The Ducks won the cup the very next year so those are late, late firsts.
Lupul vs Stajan
Lupul 701 gp 205 g 215 a 420 pts
Stajan 1003 gp 146 g 267 a 413 pts
Smid vs Kaberle
Smid 583 gp 12 g 60 a 72 pts
Kaberle 984 gp 87 g 476 a 563 pts
Stajan is slightly less offensively gifted than Lupul but Lupul is purely a one way player whereas Stajan was a both ways center.
As for Smid vs Kaberle, Smid was much younger, but, yeah, well.
So it really depends how well the Leafs picks would have been. Oh, also, Alex Steen:
Steen 1018 gp 245 g 377 a 622 pts
And Steen would likely be playing this year, which can't be said of any of the other players.
