Chris Paul and Deandre Ayton did a great job and helped the Suns beat the Pelicans this time. However, it clearly wasn't easy for them, given that the lead changed 15 times throughout the match. So you're right that the Suns are really missing Booker even though they are still the favorites in the first round. Also, the big problem for them is that Booker could miss at least 2-3 weeks due to injury.
As the commentator said at some point during the game, DeAndre Ayton did a great job to cover what are they lacking in offense. They pointed out that during the pre-game analysis that Phoenix Suns have to make adjustments in the offense since in their last game, Devin Booker made a 31 points production before the injury. That production is somehow a big loss to the Suns if they won't able to make adjustments.
Still, the Suns have an odds of @1.7 to win that game over @2.?
(I can't remember) for the Pelicans. It means even without Booker, the bookies still consider the Suns as the Favorites on that Game 3 series disregarding what the Pelicans did last Game 2, especially Brandon Ingram's big production.
