I don't think enough attention has been paid to how awful this year's rookie class has been (with the obvious caveat that Ben Simmons hasn't played yet). Aside from Embiid (who is a rookie due only to the fact he mist the last couple of years healing from injuries), the second best rookie this season has been sorta-okay 3-and-d 24-year-old super rook Malcolm Brogdan.
With that considered, the fact Malachi appears to be an actual NBA talent is a minor miracle.
