Ignorance may be bliss, but it can cost us a fortune.

Now that Big Time College Football has been returned to the New York City area in the form of the Rutgers Scarlet Knights — though one of their uniform ensembles is black — it’s time to recognize one of RU’s most notable graduates.

Friedman died in 2006, six years before a cranial bloodburst sent a relentless rush of plasma juice to the head that caused Rutgers to abandon its better senses, finances, academics and soul to join the Big Ten.
