i didnt see his sparring partner acting as a prick , it looked like normal light to mid sparring session the same we do at our gym , maybe he should refrain from grabbing your foot for now , until you feel confident in your kicking , and you both should have head gear on ,
i wont critique your sparring , im sure you are being trained well, what i will recommend is to break the habit of looking away or shelling up and turtling when you are under pressure, its a natural self defense reaction , all beginners have it , but that is what will get you ko'd, or hurt real bad ,, you are relying on your partners compassion at that point not to hit you , it will carry on until you get in a real fight and then you will get kicked or kneed in the face and not see it coming ( just like brock and overem),, always keep your eyes on him , its the only way to see the shots coming so you can block them , move your feet , get out of there , clinch him , use you knees , punch back , punch your way out , do something , , just hunching over and looking the way is a very bad habit and hard to break ,,, a drill you can do is stand with your partner against a wall or on the ropes and let him punch and kick at you , slowly at first , and concentrate on seeing the shots coming , block , parry , slip , check and counter back , its a good drill
