I agree, I really don't see Colome as netting a substantially better return than Soria (it will be better but not tiers better).
I was kinda intrigued by the idea of Joe Palumbo from texas as a return, but looking at his pitch data from his start, uhhh, he's got a nice rising fastball but his secondary stuff sucks. I don't really know the minimum return I could put together for Colome, but I don't think it will be there regardless. Like just don't let the brewers give us their trash again.
