Is there a reason why these two cannot get into contest shape? 
YES THERE IS....
If the problem is not identified then it can not be fixed.
These guys really really think they are shredded, no body can tell them otherwise, they will not listen and they will say ''you guys don't know what you are talking about''
My friend talked to Cedric after his last poor showing and he said, he couldn't get rid of water, he couldn't get full, yada yada yada. No Cedric you were fat, not water, fat.
you hear in interviews saying that he nailed his conditioning and he went bad in other areas. They think they are ''andreas munzer shredded'' and that is the problem.
