Most NBA fans still haven't moved on from the blockbuster trade involving Anthony Davis and Luka Doncic. Everyone was caught off guard when the LA Lakers and the Dallas Mavericks engaged in a trade, switching star players before the trade deadline. In the book "A Hollywood Ending: The Dreams and Drama of the LeBron Lakers," Yaron Weitzman details what happened to the LA team.No one thought the Mavericks would trade a star player like Doncic, who has repeatedly expressed his loyalty. The Slovenian star was looking forward to spending his entire career in Dallas.On the other side, Davis looked like he was untouchable, just like his teammate LeBron James. He soon realized the business side of things when he was dealt to Dallas, despite helping the Lakers win a championship in 2020.In the book, it was revealed that it was Bronny James who broke the news in the team's group chat. He sent the tweet from ESPN's Shams Charania, who was also surprised about the deal."Did these n***** just trade me?" Davis replied in the group chat.James was taken aback and only had a three-letter response."WTF?" the four-time champion wrote.The team's third option, Austin Reaves, knew how much Davis loved to pull pranks on his friends and teammates. Reaves thought that it was one of AD's practical jokes."Ok guys, AD is bullsh**ing with us."Unfortunately for the Lakers, it wasn't a joke on them. Charania soon confirmed that the deal was official and that Anthony Davis will be the newest star for the Dallas franchise.AD is set to play his first full regular season with the Mavericks this year, just like Doncic.Deandre Ayton is expected to play more like Anthony Davis this seasonAfter the blockbuster trade last season, it took a while for the Lakers to have a replacement for Anthony Davis. They had to settle with Jaxson Hayes as the starting center for the rest of the year. The team then had to sit him down and opt for a smaller lineup in the playoffs against the Minnesota Timberwolves.Over the summer, a reliable starting center was what the team made sure to pursue. As a result, they were able to sign big man Deandre Ayton to a two-year contract.The former No. 1 pick is now officially the new center for the team.However, the Bahamian center is often criticized for his lack of defensive dominance. This year, his new team wants him to play like their former star big man, Anthony Davis.Spectrum analyst Chris McGee said that DA needs to play more like Davis.“For him, the key is defense. You lost AD months ago. He’s not coming back. Very, very good shot blocker, always a top five, maybe top 10 shot blocker in the league," McGee said.For the Lakers, Ayton's defense could be the x-factor for the season.
