Leaning on him isnt working,and tighten your hands becuase he's freaking murdering you with those elbows and uppercuts.
Try going away a little,and for the love of god,if your going to go behind his head stop doing it to Cortez's side,because he's seen every single one of those,but he isnt seeing Floyds elbows,because of those shots you keep throwing in his line of sight.
Every time you try to go behind the ear,Floyd counters with an elbow,so all Cortez is seeing is your shot behind the ear.
