Yeah, that could be attractive, but 2 years 39m with Abreu vs 4 years ~66m with Beni is rough. If they ate 20m of Beni's deal at 5m a year to help with cap/tax relief, I could see that helping the deal. A little bit more costly over time for Houston, but you get a guy that's batting close to .200 vs a guy going even lower from ~.070.
I doubt the rebuilding White Sox want to send any prospects with him, honestly their best asset right now is cap space. They should be like the Mets who built up their farm last year by using cap space to facilitate trades for some good prospects. Maybe they could be interested in an up-and-coming Jake Myers, a dynamo prospect in Forest Whitley and a slightly used JP France to include some better players like Luis Robert! He has a lot of health issues, but we don't need him to play 150 games every year...
