The two wild cards to me in a Finals with Dallas is Porzingis... and Holiday. Holiday is somewhat unique in that, while he isn't a consistent 20+ PPG scorer he can still bully most other guards and I think he could do the same to Doncic/Kyrie. That can also open things up for the others.
Porzingis meanwhile is easily the best frontcourt player on both teams. I can't imagine he'd be missing these same shots as Gobert/KAT this series, although I guess if KP is still hurt or very rusty it *might* be an issue but I doubt it.
The trio of Jaylen, White and Holiday will definitely offer more of a resistance to Doncic/Kyrie than whatever I've seen from these West teams. Minnesota in particular still doesn't seem to have any clue what to do and even when they try something, they for some reason revert
