This one works on ESPN's trade checker:
Barbosa, $50 million*, and all of their draft picks for a time machine.
Amare for KG.
*: $50 million + KG's salary (including extension) funded by the 2009 stimulus package.
Seriously, though, what do people think about trading some kind of youth/picks for Jared Dudley? Is he better (for this year) than Walker? I haven't seen a ton of his games but he hasn't looked bad when I have seen him.
