I agree with the title - Tatum's style of play is concerning. He is playing with a level of entitlement that usually doesn't come until you reach ~30. Unfortunately, he also has no idea that when your team is down by 1, you only need 2 to win. This is his go-to going back to the MIA series.
Obviously the sky is the limit for the kid, but he is just too afraid to get his hands dirty. I really hope he can become a lot more mentally tough.
