This is how I see 165 going:
Hamiti pushes the pace, but as noted by @hammerlockthree, the has a hard time getting savvier wrestlers to bite on his fakes and his movement. He has to find a way to create offense without that. I predict O'Toole gets the first takedown, but Hamiti will get at least one of his own before losing by a score of about 8-5. You can take all of this to the Cinnabank
