Well if the losing doesn't stop someone has to get canned and that someone isn't at all likely to be good 'ole boy Walt. Perhaps they think they will get away with canning Jacoby at some point and lay the blame at his feet, who knows. But Dusty is no lock although I could certainly see reasons why Bob might keep him, seeing as how Bob knows little. That said money walks and you know the rest. And Edwin especially if he has a big season with the bat will be due for another big increase next offseason and the offseason after that he'll be a FA (right?). Money will force him out the door regardless. And if Frazier can get some meaningful time at 3B this season he's a certain lock for 3rd (plus any other open spot) next season. He has enough experience at SS and has the kind of intangibles that could equate to a rather quick move to 3rd.
I'm not saying it's a lock but I'd lean heavily in that direction. SS who knows, but I doubt that decision will have much to do with the other in reality.
