because they illustrate that dorian, while well conditioned, still had bodyparts that look like soft dough. And in a sport based on the comparison of appearences (not mathematical body fat percentages and the like) this would hurt him GREATLY against 99 Ronnie..
If you prefer, I can use 93 shots that show the exact same thing:
you guys always cry "its a 96 shot or its a 95 shot!"
problem is, you are too delusional to realize that he looked exactly the same at his very best in 1993... 
The best part if your ignorance is easily proven wrong ' soft dough ' lol and the best part is you having the balls to refer to Ronnie 1999 as the reference to dry & hard LMFAO it doesn't get any easier than this
MuscleMag International Feb 1994 on Dorian Yates at the 1993 Mr Olympia
" He's huge , absolutely HUGE ...
he's ripped completely RIPPED. And while he's not in possession of the prettiest physique body by a long shot , he's equipped with all the bodyparts you need to win .
Combine this with the fact that he's 10 TIMES more impressive when you see him onstage at the Olympia than he is in pictures or on videos and you got yourself a winner.
I.F.B.B. judge Roger Schwab
Man-mountain Dorian Yates was certainly the top gun in the 1993 Mr Olympia shootout. He was much bigger , better and
harder than ever , and while his is never the prettiest physique on stage , he's assuredly the most God-awful muscular superman this sport has yet seen. Though Yates was lighter than Lou Ferrigno or Paul Dillett , he appeared to be the biggest man on stage-by far- and the hardest , dominating from beginning to end and every step in between.
This is coming from an I.F.B.B. judge it just doesn't get better than this lol man I'm fucking good lol
