Ray - it's hard for "Diesel" to stay inactive for 4-6 months between UFC fights. He's "hungry" and wants to showcase his awesome skills in RITC for his hometown fans.
i have only seen one of roberts fights, so its hard to tell, but my guess is rivas by early round one ko, or late second round tko.
Robert by split decision if he does wins... Good luck to both of them.
I think Rivas will catch Robert if Robert is out of shape. Robert could win a dec, but I am thinking Rivas on this one. If and when Varner fights Rivas, I have Varner by sub in rd 1 or 2. I also want to see a Elbe/Rivas rematch. JPET SET IT UP!!!
