Just going off the first minute.. where's your jab lad eh? You want to maintain and control distance, get a killer jab/straight lead and lead with it not your back hand. Work your other striking off that. You know what a wrestler wants to do, so try and put it on your terms. IOW try to gain the time and distance that will make him fail. And of course more wrestling. Using the lead strike will also bring your reach advantage (in that fight) to your benefit. Frankly you were wasting it leading with the rear hand.
