I've heard no such rumblings. I also don't think it would cause any angst if true or not. They are both champs. I can see them both at their current weight, and I can see them switching weights as Cenzo has a body type that could support more weight without losing anything in the process. I think both guys would support the process.
As for Bubba, he chose confrontation regarding redshirting, and that's never a wise choice in any facet of life. He may have beaten DT when it counted, but I think we all know who the better wrestler was that night and every day both before and after. So, the situations were entirely different as you probably already knew when you posted.
