Cody Stamann says the Alejandro Perez that Song Yadong starched is a shell of the man Stamann beat at UFC 235.
There is an interesting road to Stamann vs. Yadong at UFC Washington on Saturday. Yadong was scheduled to fight Perez in March but pulled out of the fight. Stamann stepped in on three weeks notice and beat Perez by unanimous decision at UFC 235. Perez vs. Yadong was rescheduled for UFC 239 and Yadong knocked him out cold in just over two minutes.
Compare those two fights and you could reach the conclusion that Yadong has the advantage going into UFC Washington.
