It's kind of a big jump to the next spot in scoring but I do expect him to move up. he will easily reach the top 10 in rebounds, assists and blocks next season, it will just depend on whether or not Okeke passes him in those as they are very close in all (Chuma actually has a slight lead in rebounds.)
If, like many, you don't include Toney Douglas (i do) then he'd technically be 9th.
FWIW the list is Barkley, Mike Mitchell, Chuck Person, Eddie Johnson, Wesley Person, Chris Morris, John Mengelt, Marquis Daniels, Toney Douglas, Isaac Okoro. Those same guys make up most of the top 10s statistically, give or take one here and there.
