Worst case scenario is he is as bad as Bush which we are putting up with anyway. I will post it again: ERA, Last 3 Years: Bush: 4.41, 5.12, 6.56 Weaver: 5.76, 6.20, 6.69 (AAA) Weaver being as good as Bush is the worst case scenario? Give me one good reason why I should think Weaver is even AS good as Bush. And even if we think that the Brewers only have a 1 in 3 chance of winning when Bush starts, that doesn't mean that it might as well be zero. Far from it. As others have pointed out, Bush's peripherals have been pretty bad this year, so his bloated ERA has certainly been earned so far. That said, just making random moves and hoping for the unexpected to occur is no kind of solution. If that's a viable strategy, you might as well leave Bush in the rotation and hope he starts pitching like he did in 2006. Expected? Of course not, but it's possible! If Melvin wants to find a replacement for Bush that is clearly more talented than him, I think that he'll have to acquire him via trade. Of course, I'm assuming that McClung predictably bombs in the starting rotation and Villy gets his spot back. If I'm wrong, I could see Villy taking Bush's spot if Bush is still sporting an ERA over 6 in a month.
