Here's a great graph detailing all the A's on the 40 man roster, plus some prospects who aren't, and the A's extended control over them, courtesy of Ken Arneson over at Catfish Stew. Very helpful for visualizing the future of the team for the next 8 years.
The guys over at Hardball Times think the A's did pretty good in the Haren trade, although without adding any real insight into any of the prospects. I think the general consensus is that...no one knows if Beane came out ahead or behind on this deal. I guess we'll all just have to wait 2 to 3 years and see.
That's all I've got really, I've just been dying to add that graph of A's players all day, and no one could help me out, so I did it myself. Nyah!
