Posted this on another thread but ill repost it here.
His spurts and inconsistencies probably have a lot to do with his off court activities.
i just looked up Tatum's stats. they are kind of interesting. He is averaging 9.4 points per game. In his last 10 games, he has scored in double digits 5 times. In the last 5 games he has scored in double digits once. Its like he does everything in spurts. He will have spurts of double digit games then spurts of single digit. After looking at this, i am more inclined to think he suffers slumps and doesnt necessarily need to be benched or is "the biggest disappointment". also that may be why Bruce isnt saying anything about his play.
