Remember Sammy said even bosses from other cities were reaching out to him

Psychology helped Gotti massively... He convinced people he was the real deal
& they all fell for it (like others have mentioned) even those more qualified than he was fell trap

At weddings even when he was a capo guys were lining up to be in his presence. People were praising him behind his back "have u met this guy?"

"Nice guy".... "He's gonna be somebody someday u watch"
