To be fair, I do think that version of Cox beats this version of Zahid, but the reasoning(s) are due to matchup. I think Cox was just too defensively sound and explosive that Zahid wouldn't have been able to get his offense going. This Zahid likely beats all the same people that version of Cox did.
This version of Dake verse this version of Zahid is probably close to a 50/50 toss-up, honestly. They should both be considered the favorite(s) and honestly I am looking forward to seeing how PK does against Dake, being as just a few weeks ago PK was a VERY large 184lber and last summer Dake was a 74 KG (163lber).
That version of Cox against the version of Dake was probably also close to a 50/50, but they're both very defensive wrestlers. That means the bigger, stronger, and more explosive one is going to win more often than not, and he did (2 of 3)
