What do you think he would weigh at 5% BF?
Pretty hard to tell because there are a few important factors here...
a) I don't know how tall he is and how much he weighs in that kind of condition
b) It highly depends on how successful his preparation would go
c) Are we talking about 5% bf contest shape after getting rid of any excess water?
d) Pretty hard to judge the legs in that kind of shape because it's hard to tell what's muscle and what's not
Assuming that he is average height (5'11") and his diet would be perfect so he would not lose too much muscle in the process of dieting I guess he could come in at around 195lbs contest weight. I'm this height, my lower body is most likely better than his or at least the same size but his upper body has a lot more muscle than mine and when close to contest shape I am around 185 minus probably another 8-10lbs of water would put me at ~175-177lbs ripped to shreds.... since I think he carries a lot more muscle on his upper body I'd think this might come close... or maybe I'm totally off I don't know, I gave it a try

... and to those who say that 195lbs contest weight is nothing, can be achieved naturally or at least by anyone with some gear - take a look at Go4It at 160lbs and think again. 195lbs contest weight on average height is pretty damn impressive.
