Reggie Nelson, SD Killer.

[Joelist]

It shows that while we don't often trade we're pretty good when we do.

David Jones for Reggie Nelson

Pete Johnson for James Brooks (as mentioned upthread)

Then there was a D lineman named Orien Harris. Signed off the street than traded for Brian Leonard. Then signed Harris again and actually did some backup duty

And if we count draft picks acquired by trade it gets even better :)
