Who are they gonna find to fight Luis Santos right now? Who are the best unsigned guys that could challenge him? Watched his last two fights today on YouTube and looks like this dude is hitting his stride at 70+ pro fights. Dude is vicious. 
He has certainly looked impressive. Ricky Rainey and Dhiego Lima fight In Sept for the XFC. I don't see him walking thru either of those guys. His next fight should be a lot more interesting. 
A return to Bellator is more likely. He's earned another WW tournament berth with 4 straight R1 KOs
