At this point, the point has been well discussed that it did not make a lot of sense for the Pittsburgh Pirates to not trade pending free agents Francisco Liriano and Melky Cabrera. The team is out of contention and could have brought in value that could help down the road. Instead, they will have two veterans taking up roster spots on a last place team.
The other issue with this is that it is blocking players from getting a chance to be promoted. For instance, if Melky Cabrera would have been traded there was a good chance we would get to see outfield prospect Jason Martin return to the big leagues.
