I think Ramy has as good a chance as anyone to dethrone Phil. He has gained a huge fan base and the "powers to be" seem to be feeding the hype judging from the Flex cover.
Ramy didn't peak for the Arnold. He was probably 85% and was good enough to win, but he didn't go for it on conditioning. One presumes he and Farah have it all planned out and he will truly peak for the O. If he nails conditioning and has the size and completeness he displayed at the Arnold, Phil is in trouble.
