NY Yankees superfan Artie Lange says Alex Rodriguez has been a disaster in the Big Apple -- calling him a stain and a poison ... who's supercharged the downfall of a once proud franchise.
"I didn't want him from day 1," Lange said ... "What did we get, one extra ring with his legacy?"
"A-Rod is a stain, he's just a poison."
Lange goes even harder -- trashing the current players as money-hungry sellouts who care more about a check than continuing the Yankees legacy.
