Griggs has alot of heart and Diabate's striking is pretty severe, should make for a barnburner.
I like Diabate for this one because he works so well from the periphery and has some massive size advantages in this fight. I think he outpoints Griggs for the first two, and potentially gets the stoppage in the third with his gnarly muay thai.
