Arnold would still be big.
I don't think any of the current pros would be a big one, most folks that have been around the hobby for sometime understand that it is a risk filled one.
The only thing that might give it pause is an on stage death at either the Arnold or Olympia. That might cause some reflection for those in the hobby, much in the way that a boxer dying in the ring or a footballer taking a bad hit does. At least for a few days.
