hmm..full keeper? Id rather keep Larsson over Kabs/Zidlicky/Seidenberg
But I see where your getting at, you'd want to offer the young/potential players to a rebuilding team.
Maybe get a sense first of what he would want? Maybe he'd prefer the "name player" in Kaberle and Zidlicky - proven 40+ pts dmen over the rookie.
If I had Iggy and rebuilding..Id jump all over Ennis/Larsson. With that said, might be too much to start off.
