I'm brand new to this board, but I'll chime in on your post.
First off, I was unable to view your league as I'm not a member and it's a private league. However, if this is a keeper league and depending on the particulars of your scoring system, I would do the trade. Abreu is like a mini-Beltran, and Crawford is the second-best base stealer in the league without the worthless bat that Podsednik has. Furthermore, I just have this nagging suspicion that Barry Bonds will be exposed at last. I can see him playing about half of the games, getting walked a lot less, and having a very good but not unbelievable year (no more .800 OBP).
Just my two cents. Then again, I came in dead last in my leagues last year.
