Ok, here is my real prediction.
Both come out very tentative. Brock fakes takedown attempts and throws some right hands. Reem jabs and circles. Crowd starts to boo. Goldie takes a "bathroom" break to do some more lines so he can shout for 25 minutes. Rogan talks about Reem's underrated ground game and his K1 experience, but that Brock is a huge viking and if he gets a hold of him it could be all over. Round 1 ends.
Round 2, continue to throw jabs and circle. Getting sleepy. Crowd booing. Brock goes for takedown, Reem sprawls and holds him off at first but finally goes down. Holds him tight and gets stood up. More jabs. Rd 2 ends.
Round 3, future is too sleepy to see clearly.
