Its weird that in WCW he looked much taller and in most of his first WWE appearences. Then he piled on the weight and that has the effect of making him look somewhat shorter than he actually is. He's really just being bounced around right now heel to face over and over and over. It never really comes as a suprise when he does turn heel as the buildup to it (if any) is usually very obvious, and its been done so many times its just "meh, he turned again". The shock value of him turning died long ago.
If he could drop the weight again and bulk up in muscle somewhat then they could essentially "reboot" him.
Benoit almost gets sent into orbit with that chokeslam.^
