Don't give him Ichiro, the BA/SB combo he provides is ridiculous, he can single-handedly prop up your BA.
As far as Jones for Vazquez, I have a question: is it a daily change league? If so I'd do it, getting as much quality pitching as possible is huge. However, if not I wouldn't deal Jones. I'd try to move either Bay or Crawford, who have been playing way over their heads, for a top pitcher if I'm moving one guy. Your offense is good enough to sustain the dropoff you'd have from either of them to Jones, and you could get a top-10 pitcher in return as opposed to Vazquez, who just never has top numbers.
Any help here?viewtopic.php?t=391363
