Found this post on Hogville (the Arkansas forum)
247Sports just did an update of its 2018 rankings (actually, seems like that site tweaks the rankings once a week) ... as of now, 247Sports rates DJ the No. 52 prospect, a 4-star, but that's likely to change once all the updates are made ... his composite (aggregate of the 4 major services) is No. 200, a 3-star ... after missing 18 months with the knee injury and still playing monitored minutes since returning 6 mos ago, it's almost impossible to rate him.
My personal view is that DJ is a very good basketball player, I'd say top 75-100 if fully healthy. Had he not missed so much time (which severely limited his development), he might be Top 25-50.
