Simply put, Giannis has beaten playoff teams without much contribution from other players. He doesn't have to expect them to hit open shots. Tatum can't. Miami can put the clamps down on Tatum - see the second half of the game today. The Bucks defense against three point shooters is to let them shoot. That is conducive for Tatum's style of play. But to be honest OP you shouldn't be at this level of understanding the game.
