I think juggling the 40 man is definitely the biggest challenge, especially with respect to trades. It would be nice if they could ship out a couple of members of the 40 man and one or two other players in exchange for Bleier and one of Detwiler and Garcia from the Marlins.
The Astros just have so many guys on the 40 man that are hurt or are of questionable value moving forward. Are guys like Abreu, Smith, James, Pruitt, and Stanek really going to help this team win games this season? I still like Abreu's long-term outlook but he may not be ready yet. James apparently has totally overhauled his mechanics this year so who knows what he'll do. Smith is old and the stuff doesn't seem there anymore but they owe him money and I doubt someone like James Click wants to eat it and release him. Pruitt - who the fuck knows? Stanek looks great one night and an abomination the next and overall has been pretty shitty. Hartman, Garza, and Jones seem like filler that you can simply release and make it through waivers if need be.
