This grandma may be the biggest Miami Heat fan out there.
The Heat fan grandma was taped while she watched Game 4 of the Eastern Conference finals. Miami beat the Indiana Pacers, but it wasn't a relaxing night for this fan.
She isn't afraid to speak her mind, whether things are going good or bad. Better yet, she knows that LeBron James should be getting the superstar treatment from the referees.
Way to go, Heat fan grandma. Fans like you keep games interesting.
