Ok so lets actually break down your math for a second here. According to your numbers 63/77 strikes land giving him a landing percentage of 81%... Thats hardly bad. Also if hes thrown 77 kicks in 80 minutes of fighting hes throwing a kick slightly less then once a minute on average... So... I dont know if your numbers are supporting your thesis. Now if you want to argue that his kicking game is less effective in terms of producing knockouts this is clearly the case. But it does seem to suffice as a means of complimenting his hands and adding to his arsenal.
