Rumble cant go 3 rounds let alone 5. If it goes passed 1.5 rounds, its DC for sure.
Weidman/Vitor is going to be interesting. Vitor by quick KO, or Weidman by 3 rounds of murder. Remember Vitor back when he was just the new old vitor after he was the new vitor but before he was TRTitor before the Anderson fight still wrecked franklyn. and he didn't look like much of a rolling death machine back then. so anything is possible. but that was 6 years ago
Id say Burkmann has a shot against Donger
