Yeah, there's a pretty giant gap between 20th ranked defense in the NBA and the worst defensive season of all-time. The offense was legit good for most of the year and there's still upside on that bone with Fox/Hali and maybe even longer shots like Bagley/Metu/King still improving. There's no reason with TD/Harkless/Len/Mitchell/TT defensive upgrades this team can't be in that 18-22 range defensively. Especially if Mitchell comes out the gate as a unicorn perimeter defender.
