If New York Knicks sensation Jeremy Lin wasn't a big ass deal before, he sure as hell is now -- because Manny Pacquiao tells TMZ ... even HE'S Linsane in the membrane.
Manny was on his way into Loews Regency hotel in New York yesterday -- we asked if he's succumbed to the wave of Linsanity sweeping across the planet, and the boxing legend said YES ... claiming, "He's good ... from Asia."
DID YOU HEAR THAT?!?!?!?!?!! Manny Pacquiao said Jeremy Lin is GOOD!!!
We need some air.
