A lot of people acted like Royce had no chance, but a lot gave him a chance, and I'd say Royce was the favorite amongst casual fans that I knew.
The majority of fans were so clueless they introduced Royce as undefeated (and included his non-UFC wins, but not the loss to Saku in his record)
He didn't fight Ologun.
Tokoro is no slouch. And he had a big speed advantage over Royce being smaller and younger. A lot of people said Hughes wouldn't be able to do what Tokoro did to him, and they were right about that. Hughes didn't rely on speed.
Royces only somewhat recent fights were against Akebono (huge SHW) , Tokoro (BW) Yoshida (HW and Olympic medal winning Judoka) and Sakuraba (legendary grappler and they went 90 minutes) The 3 most recent were in K-1 so even most hardcore MMA fans didn't see them, let alone the casuals.
He hadn't fought any WW's recently and he'd done well against other larger elite grapplers. There was nothing to go on, in terms of similar opponents or MMA math, so for those who hadn't seen his recent fights, it was perfectly reasonable to think Royce could win. Even though it was a foolish opinion.
