Considered one of the favorites to be taken first, Noel instead fell to No. 6, where the New Orleans Pelicans took him and then dealt his rights to the Philadelphia 76ers for a package headlined by All-Star guard Jrue Holiday, according to a person familiar with the details.
The Cleveland Cavaliers started things by passing on centers Noel and Alex Len, who went to Phoenix at No. 5, in favor of the UNLV freshman forward who has starred for Canada's junior national teams and was the Mountain West Conference freshman of the year.
There was suspense right until the end, either because the Cavs were unsure who they wanted or were trying to trade the pick. Most predictions had them taking one of the big men, with Noel largely considered the favorite for the No. 1 choice even after a torn ACL that ended his lone season at Kentucky in February.
David Stern, booed heavily in his final draft as commissioner, added to the surprise of the moment by pausing slightly before announcing the Cavs' pick, their first at No. 1 since taking All-Star Kyrie Irving in 2011.
"I'm just as surprised as anyone else," Bennett said.
Orlando passed on both of the big men, too, going with Indiana swingman Victor Oladipo with the No. 2 pick. Washington took Otto Porter Jr. with the third pick, keeping the Georgetown star local.
Ten years after the Cavaliers selected LeBron James to start a draft that would include his future NBA championship teammates Dwyane Wade and Chris Bosh in the top five, this one lacked star power and perhaps even the promise of stardom.
Bennett, Noel and Len are all coming off injuries and couldn't even work out for teams, but the Cavs decided Bennett's shoulder surgery wasn't enough cause for concern.
Len walked up to meet Stern and collect his orange Suns hat, then sat down near the stage to put on the walking boot he needs for the stress fracture of his left ankle that was discovered after Maryland's season.
Noel finally went to New Orleans with the next pick. He didn't seem upset at his fall down the draft board, hugging his mother and shaking hands with Wildcats coach John Calipari.
It was a good start to the night for the Hoosiers, with Cody Zeller going two places after Oladipo to the Charlotte Bobcats.
Kansas guard Ben McLemore, another player who was considered a potential top-three pick, also dropped, going seventh to Sacramento.
Headed by a lackluster class, the draft promised confusion and second-guessing, with no consensus No. 1 pick and little agreement among the order of the top five.
And with lesser-known names in the draft, veterans soaked up the spotlight in the hours leading up to it.
Hosting the draft at Barclays Center, the Brooklyn Nets made the biggest news. A person with knowledge of the talks confirmed a Yahoo Sports report that the Nets and Celtics were working on a trade that would bring Paul Pierce and Kevin Garnett to Brooklyn.
ESPN reported earlier Thursday that Dwight Howard was unlikely to return to the Los Angeles Lakers when he becomes a free agent next month.
The guys coming into the league were glad for the attention they did finally get once their names were called.
"It's like a weight vest you took off after running five miles," Oladipo said. "It's relaxing, man. But at the same time, you know it's just getting started."
National player of the year Trey Burke of Michigan also was traded, the Minnesota Timberwolves sending his rights to Utah for the 14th and 21st picks, according to a person with knowledge of the details.
Lehigh's C.J. McCollum rounded out the top 10 by going to Portland.
Stern, retiring in February, seemed to play up the boos, which turned to cheers after every pick, fans perhaps as puzzled as some of the players at the names they were hearing.
"I was just kidding my agent because he didn't bail me out," Zeller said. "He didn't tell me. I didn't know until David Stern announced it. It's a crazy process not knowing, but I'm definitely excited that I ended up with the Bobcats."
