I hate change when it's not warranted, like now. Since April I've been of the mindset that the Angels are a bullpen move or two from being a serious contender. This offense was effective even with Ibanez in it. Now that he's gone, it reasons that the offense will be better.
There is absofreakinglutely nothing to be gained from casting Scioscia off to the side.
If you have a time machine and would like to jump back 3-4 years in time to start a "Fire Scioscia thread," have at it.
