The sad thing is on Smackdown everytime they seem to get a new champion then they pick up an injury or get suspended,I don't think that Rey would have been champ if Randy Orton was still active in the wwe,But with Kurt picking up another injury and Batista still not full back on the active roster there were not that many other choices for the management.
Rey has always been a great athlete and always managed to shine in the ring even with the super heavyweight opponents but i do agree that that it does not seem a good idea for him to be Heavyweight champion...He would be an awesome Intercontinental/US champ but just not World champ.
