Big shows improved a ton over the last year or more, i think its safe to say he IS the modern day andre in a lot of ways. If he could cut his weight down he'd have a ton more longevity in wrestling, looking at him in wcw when he started he was probably around 350-400, he got an operation to stop that disease that he had and his metabolism slowed and his weight ballooned.
Saying that though it would be better if he did go out when he was still a good performer, seeing how andre went in his final years was just sad, he pretty much had to spend a load of the match hanging onto the ropes and rely a ton on *rest holds* (*see: Orton, Randy) .
