Other than Gus, which bigger fighters did he struggle with? He ran through Bonnar, Vera and O’Brien. Sure they’re lower level fighters but size didn't seem to have helped them at all. He struggled with Santos (MW) and Reyes more than anyone else, and to be honest I think that’s due to USADA.
Stipe’s boxing is the thing I imagine being a problem for him.
Gus sent him to the hospital, a lot of people think Reyes won, he didn’t look impressive at all against OSP, Santos nearly has HW reach with his arms & legs and that gave Jones fits.
