I wish there was a good site that showed all of the picks a team owned for a certain draft year, and where those picks came from.
I say this only because with the 4th rounder from the Lombardi deal, the Leafs may end up with three 4th rounders in the upcoming draft. Their own 4th rounder, Phoenix's 4th rounder, and possibly Anaheim's 4th rounder. The Lupul deal included a conditional 4th rounder that will be awarded to Toronto if Lupul plays ~40 games for the Leafs this season.
It would be pretty interesting to trace every pick's movement.
