Teams were still negotiating through sherm the werm. That fat snake may have identified the targets for him but shermy brought them in. His role gets played down a lot and until we get some tell all books confirming who actually did what, I'm not ready write off all that happened in his name. Especially since everyone was so willing to blame shermy when the trades first came out and everyone was freaking out at him about overpaying.
Edit: as an aside, why do people dislike accountants so much? They do terribly boring jobs that allow the rest of us more interesting pursuits. If anything accountants should be respected, like the people who wiped the king's ass in days of yore, a horrible job that it was important to have someone do.
