The Suns have really dominated for much of the NBA season, including the playoffs where they have taken down the Lakers, Nuggets, and Clippers. All three of these teams had significantly better preseason title odds as shown below.

Now with Giannis and Trae with uncertain injuries, I honestly don't think either team is capable of beating the Suns. However, I also didn't think it was possible for the Sixers to lose to the Hawks either. I guess a better way of saying it would be it is most definitely the Sun's title to lose.
If the Suns were to win, I think the storyline will be how great of a basketball player Chris Paul is. One of my favorite graphics ever is the one below showing "The Chris Paul Effect".

This guy is a no-doubt hall of famer, and I would argue he is a top 3 PG of all-time (behind Magic and Oscar Robertson). 
Although my team, the Sixers, got bounced early from the playoffs and I have been living in basketball misery ever since the Hawks outscored them 42-19 in the final quarter of game 6 of the second round... I truly am happy CP3 and the Suns are having the success they are and I hope they come out on top.
