He might be one of the toughest guys in the NBA, but Sacramento Kings player Reggie Evans has a soft spot for his kids ... as evidenced by the adorable chain he rocked around NYC yesterday.
Evans -- who was in town to play the Brooklyn Nets -- headed over to the Barclays Center with several diamond-encrusted pictures of his 4 kids.
C'mon ... that's cute and you know it.
Evans was also rocking out a pair of fancy Louboutin boat shoes ... $1,200 a pair.
But the necklace -- that's priceless.
