I want to see him box, concidering the piss poor hw talentpool in boxning these days
Rumble doesnt deserve for this fight. He last fought couple years ago at 205 when he lost in similar way to Cormier second time. If Rumble wants to comeback he have to fight with someone from top 10/15 first.
Rumble is huge now and he has done lot of bodybuilding training what is very bad for MMA fight.
Currently Rumble is slower than Francis and I bet his cardio is worst.
Rumble needs to loss some muscles and do real strengh cardio training at least few months to prepare his body to at least 15minutes MMA fight.
MMAs HW talent pool is even worse though. Either guy would be fringe top 10-15 at best in boxing.
