I'll make this short and sweet (although "brief and bitter" is probably a more apt description).
"Insanity is doing the same thing over and over and expecting a different result." That quote is often attributed to this man:
Some say Franklin was the first person to utter that sentence. Others say it was Albert Einstein. But Wikiquote says it was more likely 1980s author Rita Mae Brown.
No matter. The point is the quote fits perfectly with what the Yankees have been doing this offseason.
