Willis Reed was the first pick of the second round in 1964, but he was the 8th overall pick. Moses Malone was drafted into the ABA and not the NBA, and he was taken in the third round, but there were only 10 teams at the time, so he was picked earlier than Jokic, even if it was a later round.
Outside of Jokic/Malone it looks like Nash/Giannis (both at #15) were the lowest-selected MVPs.
