0 shots from Tatum in the 4th.
Not soft at all
He certainly needs to be more aggressive in those situations and demand the ball in this awful equal opportunity offense, even though that's not really consistent with his character.
That said, a lot of this issue is contextual. First, he only plays half of the fourth quarter thanks to this year's awful rotation pattern, which makes no sense to have your best player limited in playing time when it matters most. Second, the others have been so bad that they're sending tons of help and double teams Tatum's way any time he makes his move, and though he's setting others up nicely, they aren't able to capitalize with tonight being yet another example of a game with numerous missed potential assists from Tatum. And he's just not aggressive/dominant enough offensively to score through those double teams and extra pressure that they're bringing to him when making his moves.
