What to package with Seidenberg?

By now, you've probably heard that Nick Kypreos said the Bruins were looking to trade Loui Erikson (because he doesn't fit in on the team) or Dennis Seidenberg to free up some cap space. I don't even want to get into the Loui bit, but trading Seidenberg is interesting. It's important to take this with a grain of salt, as this is what Kypreos was known for as a player:

Anyways, I'm looking at the Leafs, and their deep pockets and 5 year plan. They shouldn't really care about salary all that much. Which is perfect, since we have some salary we need to move. I floated this idea to a leafs fan friend of mine, and his response was simple and reasonable:

@HBAdventure so what prospect are you packaging with him?

I mean, it makes sense. In the poll below, I've listed all of our Top 25 Under 25 players, minus the regular roster players. Please select the highest-ranked player you'd let go to get Seidenberg (and his cap hit) off the roster. Or in the comments, tell us what you'd do instead.
