Anyway, it's the Celtics and Mavericks in the NBA Finals. During the 2 regular season games, the Celtics won in both games. Which duo will succeed in getting a title. Will it be Tatum & Brown or Luka & Kyrie. What's your prediction? For me, I'll go with Mavericks in 7 games. 
Same, going to bet for the Dallas Mavericks in this series, good thing though that they are the underdog in this series with an odds of 2.85 as of this writing. The Mavs will be the bigger, quicker and younger team versus the Celtics so this is a easy pick at least for me.
There are some questions that are coming to my mind when it comes to the Celtics.
1. Will Porzingis play the whole NBA Finals?
2. How will Jrue Holiday defend Luka Doncic? Or will he successfully defend Luka and potentially decrease his playoff stats.
If Porzingis will play in the whole NBA Finals (it's his first time if that happens), it might be a huge factor towards the Celtics defense in the paint because of how tall he is and how he can stretch the defense of the Mavericks with his ability to shoot. TBH, both Gafford and Lively might have a disadvantage against him because I expect that both of them will guard KP at least for most of the game.
We know how excellent Holiday is as a defender and with this one, it's no doubt that he will guard Doncic. The question is how good he is at defending Luka. Will he be the one that can stop Luka for scoring 30+ points every game? Will he be the one that can stop him and decrease his efficiency? Because if he cannot then I don't think that the Celtics can win. Like KP, he also has a big role in this series, and if they want to win, he must guard Luka at all times.
Both KP and Holiday have big roles in this NBA Finals. I didn't specify Tatum and Brown because we know what they will do in the court. Still, I'll go with Mavericks in 7 games whatever happens.
