I think part of JT's struggles during the playoffs has been trying to digest all of the different schemes and tempos that coaches are employing against him - i.e., where is help coming from, when is it coming, and who is providing it (and who is not).Tatum sometimes attacks immediately when he has a mismatch; but other times he also has the mismatch and he waits because he knows the double-team is coming, and he draws it and kicks it to the open guy. It's really opened up his playmaking during the playoffs.
The play below in particular is pretty amazing to me: JT beats Wiggins but while he is doing that, he sees Green stepping up. But more importantly, I guess he sees Klay taking two baby steps down to try to do something to prevent the lob threat. JT immediately processes this to know that the wing is open and throws a strike to PP for 3P while early enough that Green has no chance to impact the play.
