You don't really have to care about what people think, you know fans (and fighters) are often a bit dishonest, but make no mistake, full camp or not, beating Volk, if it happens, is always an accomplishment.
You can't really blame Volk for pointing out he might perform a bit worse than usual, but if he took the fight, he obviously expects to be able to win.
He has to get credit for saving the card IMO, it's true I might be "lenient" with Volk if he loses, given the conditions ; but I'd still give full credit to Islam, who prepared for a totally different beast.
