Most pre-draft mocks had Jaylen going 8th. The players in the 3-8 range were seen as interchangeable prospects. Some mocks had us taking Marquese Chriss at #3. He went 8th. Had Boston taken Chriss at #3 and Brown had been taken #8 as widely expected, nobody would have been all that surprised. So before you start declaring Jaylen is the top pick in the draft after a couple preseason games, you might want to start by comparing him to Marquese Chriss.
Jaylen is averaging 8 points, 4 rebounds, 1.7 assists, 1.3 steals with 33% shooting
Chriss is averaging 12.8 points, 6.3 rebounds, 0.5 assists, 1.3 steals with 44% shooting
So maybe Jaylen goes 8th and Chriss goes 3rd... or more likely, this conversation is ridiculous right now since we haven't seen any of these rookies play an actual NBA game yet.
