Jay has a thing called a brain.
Why would he risk his health (hell even his life) when his current package is good enough to be number 1? Jay is looking towards his retirement and his days after competing. In comparison look at Coleman. The guy is a mess. His body is in shambles and he spent all his money on cars and 30" rims. Yeah, he got 8 Sandow trophies, but Cutler will have 3 and will be much more successful and healthy post-bodybuilding.
as Dorian Yates said, "if i'm not improving i'm retiring."
don't know mr cutler personally but, looking at him, i'd say he takes his fair share of bbing drugs and it looks to me like he takes them year round too.
add to that a bodyweight hovering around 280lbs + for most of the year, i doubt he's obsessing too much about the future.
