Isaiah Thomas' 53-point effort in Tuesday night's Game 2 Celtics win was impressive on its own. Add up all the things he was dealing with off the court, and it's even more incredible.

Thomas was playing on his late sister's birthday. Chyna Thomas, who passed away in a car accident on April 15, would have been 23 years old.

Thomas also underwent six hours of dental surgery the day before after having his front tooth knocked out in Game 1. Somehow, Thomas was able to overcome all of that to have the game of his life.
