MMAtown's UFC 331 predictions focus on three very different plays: Joshua Van at around 1.90 against Alexandre Pantoja, Mauricio Ruffy as a high-risk 4.00 underdog against Arman Tsarukyan, and Doo Ho Choi by KO/TKO at 2.70 against Patricio Pitbull. Van is our strongest of the three; the other two require more caution.
