There's no question Kyrie and Luka can be killers and are offensively gifted.
But I can't imagine Dallas will play as fast and move the ball around as swiftly as Indiana did. In a way I think a series with Indiana did us a solid, it gave us a little experience against that kind of offense. The Mavs run a lot of isos and pick and rolls, but they are also a lot slower coming up the court and easier to defend individually than Indiana was with all their movement, screens, etc.
If Boston decides to play with pace, the Mavs will be in trouble. The Mavs have a solid defense but it's not the kind that can shut down Boston or even a team like Indiana when the ball is moving. Now that said, if Boston continues to also play iso and settle for 3s, they can make it difficult on themselves and that's my fear. In theory though, Dallas has no one who can stop Tatum IMO. This is Tatum's time for redemption from 2022. Jaylen got his ECF redemption from last year, now Tatum can get his 2022 Finals redemption with a big series and a Finals win over Doncic's squad.
