"That dude could play right now [in the NBA], like today," one NBA assistant coach who sat courtside told SNY.tv.
"Like if he left Duke right now and said, 'I'm leaving,' he would be Utah's best player. He would be a lot of teams' best player."
For the record, the Utah Jazz are 1-9 entering Saturday's action.
Nearly 80 NBA personnel watched the Champions Classic, and came out with differing opinions on who was the most impressive between Parker, Andrew Wiggins and Julius Randle.
Magic Johnson and Jalen Rose told SNY.tv exclusively they would draft the 6-foot-9 Randle first.
One NBA GM said he would take Wiggins first.
"They're all three very different so for that GM he might look at Wiggins like he fits the profile of his team better," the NBA assistant said. "Maybe he has a couple of post players already so he's looking at the upside of Wiggins and his star power."
Kevin Durant told Yahoo! Sports that Wiggins and Parker are like 1A and 1B.
For his part, the assistant would take Parker first.
"Me personally, if I had to rank all three I've always felt that Jabari is the best player," he said.
Some questions exist about Parker's ability to guard, but the NBA assistant doesn't share those concerns.
"I watched him guard Kevin Durant for four straight days at Nike Skills Academy," he said. "Ask anybody what he did that week. He was ridiculous."
Parker projects as a top-3 pick in the 2014 NBA Draft, but longtime New York recruiting analyst Tom Konchalski posits that Parker might be persuaded to spend another year at Duke now that his friend and former AAU teammate Jahlil Okafor has pledged to the Blue Devils -- along with Tyus Jones.
In an interview Saturday with SNY.tv, Sonny Parker, Jabari's father, said the two are friends but that both players would do what's best for themselves. He added that Jabari is focused on his freshman year, which has just begun, and isn't focused on next season.
"We don't know what his plans are," Sonny said.
