Big Man of the Month of DeMarcus Cousins. He and Andre Drummond were tied with 4 BMOtN designations each during the month, so I went with team record during the month as a tie-breaker: The Pelicans went 7-8, the Pistons went 6-9. Nikola Vucevic, Karl-Anthony Towns and Anthony Davis were tied for second, with 3 apiece.
