It’s back. That deliciously dizzy feeling that madness is coming. As a rabid Princeton basketball fan of a certain age, I got used to this feeling years ago when the Tigers charged into the NCAA Tournament with regularity. Twice in the late ‘70s, four times in the ‘80s, six times in the ‘90s, and twice in the early 2000s, the orange and black danced “bigly,” as a certain Penn graduate might say.
