The definition of insanity is doing the same thing over and over again and expecting different results. In the decade-and-a-half title-less nightmare version of Groundhog Day the New York Yankees and their fans have been living, it's a very familiar definition, and it's one Brian Cashman needs to absorb.
The Yankees' long-time general manager has certainly become set in his ways, and those ways have actively held the club back in recent years. Three big Cashman habits in particular are things we'd love to see change. In many ways, they must change in order to avoid compounding the mistakes of the past any further, and get back to the baseball mountain top for the first time since 2009.
