"Wilder hasn't got a jab" Wilder-Stiverne 1 (UD12) Wilder-Arreola (RTD8) Chakhkiev-Wilder (10-11 PTS) Stiverne and Arreola were much shorter and stubbier but still longer than Ruiz. They had similar footspeed and were durable but Ruiz has less punching power. Stiverne and Arreola got schooled by Wilder's jab. Ruiz lost a controversial MD to meek stubby light punching backfoot Parker and lost a wide UD (albeit while a stone overweight and in a big ring) to a backfoot Joshua. Wilder can win this fight with a jab à la Stiverne 1 or with the more conservative Ortiz 2 tactics of waiting to set up a flush right hand.
