TJ needs to do some reflecting. He should be happy that he's healthy enough to play ball. He should be happier with less minutes so his body (health) can last longer, and the longevity of his career can be extended. All he needs to show is quality minutes and his contract will always be extended, and he will always be a hot commodity.
He also needs to remember what happened to (unhappy) Dixon, who now needs to work his way from the end of the bench and compete and fight against other bench players just to see some court-time. So, TJ should be so thankful that he automatically comes in for Calderon. If he continues to be unhappy he will find himself in another team, in the same predicament as Dixon.
Count your blessings TJ and use them wisely!
