(CNN)Zion Williamson going No. 1 to the New Orleans Pelicans may be all but certain, but the NBA draft still has the potential to be a roller coaster ride.
NBA draft 2019: Zion Williamson era set to begin
It would be crazy if New Orleans doesn't take Williamson as the No. 1 overall pick Thursday in New York. It's also assumed the the Memphis Grizzlies will select Murray State point guard Ja Morant at No. 2 and the New York Knicks will take RJ Barrett, Williamson's teammate at Duke, at No. 3.
But things got shaken up over the weekend. According to ESPN and other outlets, the Pelicans are trading Anthony Davis to the Los Angeles Lakers, sending Lonzo Ball, Brandon Ingram, Josh Hart and three first-round draft picks -- including the No. 4 overall selection -- to New Orleans (It's expected the deal will be completed July 6, so the official draft order still shows the Lakers at No. 4).
There's been another deal since, as the Grizzlies are trading their longtime point guard Mike Conley to the Utah Jazz.
Things could be interesting with that No. 4 pick. Will New Orleans keep it? Does anyone want to trade up for Vanderbilt's Darius Garland?
Williamson, meanwhile, is the most hyped prospect since LeBron James. That was apparent on Wednesday, when reporters flocked to Williamson during a media session.

In his lone season at Duke, Williamson was the biggest draw men's college basketball saw in years. Listed at 6 feet, 7 inches tall and 285 pounds, Williamson was a human highlight reel -- not just with his explosive dunks but with his all-round game.
"I don't know how I'm going to react (on draft night)," Williamson said Wednesday. "I don't know if I'm going to cry; I don't know if I'm going to have this giant smile on my face. I guess we'll see."
Coverage of the NBA draft begins at 7 pm ET on ESPN.
The Pelicans and their fans celebrated when the team won the NBA draft lottery in May. And a chain restaurant that started in Louisiana now has gotten in on the action.
On Thursday, a Popeyes in downtown New Orleans will have a "Wingspan Box" to celebrate Williamson. It's an 82-inch-long box full of chicken, with 77 boneless wings, 11 biscuits and 11 serie
