Especially for a 6 month long season you want to prevent tanking for those top picks. It could really ruin your league and you'll have to try to put a stop to it after it's been going on for a month or longer by making up rules on the fly.
Here's the offseason draft order my league uses:
12 teams - 4 teams make playoffs
Picks 1-8 will be assigned to the 8 non-playoff teams the previous year RANDOMLY. 5th place finisher has equal chance of pick 1 as 12th place.
Also, our offseason draft will be 16 rounds (multiple of 8). In round 2, the 1-8 picks will be reassigned randomly and this will continue so every non-playoff team has picks 1-8 twice each. For example, each team will have pick 1 twice, pick 2 twice etc for the 16 rounds. Mean while, the 4 playoff teams will just be the last 4 in reverse order of finish since there's no reason to tank it in the playoffs when prize money is on the line.
