The more important thing here is DB really needs to step up now. Its make or break. If he can't draw or keep people interested they will strip the title off him as quick as they put it on him. He had a cinderella moment yesterday but was injured kayfabe after his match for a reason. I don't believe for only minute that Vince wants to keep the title on him. They will use the "Injury" as a way to screw him out of the title.
I agree with everything you mentioned. I suspect it pains Vince to put his big belt on a sub-200lb, sub-6 footer. It wouldn't surprise me if it was only done to give Mania a happy ending, with them moving it onto someone else ASAP, thus relegating "Cindy" to a transitional champ.
Even so, I'm glad the dude got to wear the strap. He's a good worker, a hard worker, sounds like a nice dude, and deserves it!
