As strange as this may seem… (playoff seeding)

So question that may have been answered elsewhere. If the Saints lose to the Rams but win the other two games (Bucs/Failclowns) and the Bucs win every remaining game but the Saints, who goes to the playoffs? Or specifically who wins the division? We'd both have the same records and have split the head to heads. What are the other tie breakers?
Bucs would win the division based on common games. 8-4 vs 6-6. Difference is the Bucs went 3-1 against the nfc north and the saints went 1-3.
